Jeremiah 31:31-33 “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah — not according to the covenant that I made with their fathers in the day that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the Lord. But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people.
As I traveled across the U.S., I occasionally came across individuals who didn’t believe that Israel and the Jewish people were relevant to God’s redemptive plan. Amazed, I would show them this passage in Jeremiah foretelling how God would make a ‘New Covenant’ with the house of Israel and with the house of Judah! This scripture, an Old Testament foundation for our entire New Testament, was addressed to the two houses of Israel, yet its fulfillment in the Messiah Yeshua (Jesus) was received by only a (significant) remnant of them, at His first coming.
The apostle Paul, however, unequivocally affirms that this initial remnant of saved Israel carried the Messianic revelation to the entire world and that revelation would eventually be returned to the Jewish people in full measure;
For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in. And so all Israel will be saved, as it is written: “The Deliverer will come out of Zion, And He will turn away ungodliness from Jacob; For this is My covenant with them, When I take away their sins.” [Romans 11:25-27]
And interestingly, Israel’s future inheritance in the New Covenant is highlighted as well by ancient rabbinical commentary on Jeremiah 31:31-32;
“When the time of the advent of the Messiah will be near, then the blessed God will say to him: ‘With him I will make a new covenant. And this is the time I will acknowledge Him as my son, saying ‘This day have I begotten thee.’ [Midrash Tehelim, 3:4]
Indeed ancient rabbis saw in this scripture that the new covenant was connected to Psalm 2 and would be ushered in by the Messiah, who would be God’s own son…..hmmm.
Another ancient rabbinical commentary on Jeremiah 31:31,32 says, “He will sit and expound the new Torah (teaching or instruction) which He will give through the Messiah.” [Midrash Talpiot 58a]
So the testimony of Yeshua, the Son of God, came through the Tenach (Old Testament), Moses, the Prophets and Psalms, which are the scriptures of the Jewish people, and is even supported by rabbinical commentaries. In addition, the entire New Testament (with the possible exception of Luke) was written by Jews. This people, blessed of God in so many ways, and chastened accordingly for their disobedience, is still quite relevant to God’s plans. His “gifts and callings are irrevocable” [Romans 11:29].
God is not finished with Israel or the Jewish people. And thank and praise Him for the faithfulness of that promise, because if He remains faithful to such a disobedient nation, He will also remain faithful to all those called and chosen through the revelation of Israel’s Messiah…you and me.

[worthy_plugins_devotion_single_body]Isaiah recalls the Exodus as the supreme display of God’s Z’roah, His Arm of glory. Though the people saw Moses raise his staff over the Red Sea, it was not Moses’ power that split the waters. Behind the prophet’s hand was the Arm of the LORD — majestic, glorious, and unstoppable. The sea parted not to honor Moses, but to exalt the Name of the God who sent him. The Red Sea became a stage for God to reveal His glory, so that His Name would echo through generations as the Deliverer of His people.
Jeremiah uttered these words when everything around him looked hopeless. Babylon’s armies surrounded Jerusalem, the city was on the brink of destruction, and yet God told Jeremiah to buy a field as a prophetic sign that restoration would come. The prophet responded in awe: the God who created the heavens and the earth by His outstretched arm (bizroa netuyah) is not bound by human circumstances. The same God who set galaxies in place and boundaries for the seas is the God who still moves to redeem His people. Truly, nothing is too hard for Him.
Isaiah’s words summon one of the most dramatic images of God’s saving power: the Z’roah — the Arm of the LORD — cutting Rahab in pieces and piercing the dragon.
Here, Rahab is not the woman of Jericho but a poetic name for Egypt (Psalm 87:4), often symbolizing arrogant nations and the dark spiritual powers behind them. In Hebrew poetry, Rahab also evokes the sea monster of chaos, a stand-in for the forces that oppose God’s order. To say the Arm “cut Rahab in pieces” is to recall how God shattered Egypt’s pride and broke the grip of the powers that enslaved His people.
Psalm 98 is a victory psalm — a call to lift up a “new song” because the Z’roah, the holy arm of the LORD, has brought decisive triumph. In Hebrew thought, the arm is the active extension of the will, the power that brings intention into reality. To call it “holy” is to declare that it is set apart, dedicated fully to God’s purpose, incapable of corruption. The psalmist celebrates that salvation is not a hidden act, but an open demonstration — God’s righteousness revealed before the eyes of the nations.
This is one of the most intimate revelations of the Z’roah in Scripture. God looks for a human intercessor but finds none. No man can bridge the gap. So His own Arm accomplishes the work. In Hebrew, v’tosha lo zeroa — “His arm saved for Him” — reveals that salvation originates from within God Himself, not from any outside help. Isaiah adds that His own righteousness sustained Him — it upheld His resolve to save — and His fury upheld Him, a holy passion that would not rest until justice was accomplished.
To “bare” the arm means to roll up the sleeve and reveal the full readiness for action. In Isaiah’s prophecy, this is a global unveiling — no longer hidden, the Z’roah is on display for all nations to witness. This speaks directly of Yeshua’s (Jesus’) public ministry and, ultimately, His crucifixion.
The Hebrew phrase “z’roah moshel lo” paints the picture of an arm that governs with both strength and care. The same Z’roah that brought Israel out of Egypt in power now establishes righteous order and sustains His people in love. Deliverance without rulership is incomplete; the Redeemer becomes the King — and the King rules as a Shepherd. The Arm does not act independently but moves in perfect submission to the Head, carrying out the will of the Father.
