(7) Wall made by a plumbline--i.e., a perpendicular wall, the stability of the kingdom being represented by the closely-fitting well-jointed stones of a lofty wall. Right in the heart of this strong-built city, the Lord Himself marks the extent of the desolation, the plumb-line being used in dismantling buildings, as well as erecting them (2Kings 21:13; Isaiah 34:11).

Verses 7-9. - § 3. The third vision, the plumb line, represents the Lord himself as coming to examine the conduct of Israel, and finally deciding on its entire ruin. Verse 7. - Upon (rather, over) a wall made by a plumb line. The word translated "plumb line" (anakh) occurs only here. Septuagint ἀδάμας: so the Syriac; Vulgate, trulla caementarii; Aquila, γάνωσις, "brightening," "splendor;" Theodotion, τήκομενον. As the word in other dialects means tin or lead, it is usually taken here to mean the plumb line which builders use to ascertain that their work is even and perpendiculur (see a very different explanation in Knabenbauer, p. 314, etc.). The "wall" is the kingdom of Israel, once carefully built up, solidly constructed, accurately arranged. God had made it upright; how was it now?

7:1-9 God bears long, but he will not bear always with a provoking people. The remembrance of the mercies we formerly received, like the produce of the earth of the former growth, should make us submissive to the will of God, when we meet with disappointments in the latter growth. The Lord has many ways of humbling a sinful nation. Whatever trouble we are under, we should be most earnest with God for the forgiveness of sin. Sin will soon make a great people small. What will become of Israel, if the hand that should raise him be stretched out against him? See the power of prayer. See what a blessing praying people are to a land. See how ready, how swift God is to show mercy; how he waits to be gracious. Israel was a wall, a strong wall, which God himself reared as a defence to his sanctuary. The Lord now seems to stand upon this wall. He measures it; it appears to be a bowing, bulging wall. Thus God would bring the people of Israel to the trial, would discover their wickedness; and the time will come, when those who have been spared often, shall be spared no longer. But the Lord still calls Israel his people. The repeated prayer and success of the prophet should lead us to seek the Saviour.Thus he showed me,.... A third vision, which was in the following manner:

and, behold, the Lord stood upon a wall made by a plumbline, with a plumbline in his hand: this "wall" was the people of Israel, who were built up as a wall, firm and strong; and so stood against their enemies, while supported by the Lord, and he stood by them. The Septuagint version is, "an adamantine wall". In their constitution, both civil and ecclesiastic, they were formed according to the good and righteous laws of God, which may be signified by the plumbline; and so the Targum renders it, "the wall of judgment". And now the Lord appears standing upon this wall, to trample it down, and not to support it; and with a plumbline in his hand, to examine and try whether this wall was as it was first erected; whether it did not bulge out, and vary from its former structure, and was not according to the line and rule of his divine word, which was a rule of righteousness.
