Isaiah 4 Bible study: The LORD's branch

The chapter before ends in loss: "Your men shall fall by the sword, and your mighty in the war" (3:25), and "Her gates shall lament and mourn" (3:26). Then: "Seven women shall take hold of one man in that day" (4:1). They ask him for nothing to live on: "We will eat our own bread, and wear our own clothing" (4:1). Here is what almost everyone misses: a few verses earlier, when "a man shall take hold of his brother" and say, "You have clothing, you be our ruler" (3:6), the brother refuses, "for in my house is neither bread nor clothing" (3:7). In Hebrew 4:1's bread and clothing are the words of 3:7, lechem and simlah (the WEB's take hold is a different verb in each). The women ask only for his name: "Just let us be called by your name. Take away our reproach" (4:1) (tap reproach). The verse doesn't say what their reproach is, and these notes apply nothing in it to marriage, or to women, today.

Isaiah 4:3→leads toRevelation 21:27

This link is an interpretation. Isaiah says that once "the Lord shall have washed away the filth of the daughters of Zion" (4:4), "he who is left in Zion and he who remains in Jerusalem shall be called holy, even everyone who is written among the living in Jerusalem" (4:3). John is shown "the holy city, Jerusalem, coming down out of heaven from God" (Revelation 21:10), and says of it, "There will in no way enter into it anything profane, or one who causes an abomination or a lie, but only those who are written in the Lamb’s book of life" (Revelation 21:27). Revelation doesn't cite Isaiah 4. Some read Isaiah's promise of a Jerusalem made clean, whose people are called holy, as reaching its fullness in the holy city John saw, which nothing profane enters; others read 4:3-4 of Jerusalem after the judgment of chapter 3, of those left alive once the Lord has cleansed the city, and leave Revelation its own words. This line doesn't say whether Isaiah's "written among the living" is the book Revelation names.

Brown-Driver-Briggs: "sprout, growth". Strong's: "a sprout (usually concrete), literal or figurative". "In that day, the LORD’s branch will be beautiful and glorious" (4:2). The Hebrew Bible has it 12 times, twice in Isaiah. The WEB gives it as "that which grew on the ground" (Genesis 19:25) and as bud in "For as the earth produces its bud" (Isaiah 61:11). In Jeremiah and Zechariah it is Branch, of one the LORD raises: "I will raise to David a righteous Branch" (Jeremiah 23:5; also 33:15), and "Behold, the man whose name is the Branch!" (Zechariah 6:12; also 3:8). It is not the word of "a branch out of his roots" (Isaiah 11:1): that branch is another Hebrew word, netser (Strong's H5342).
