Kommentar zu Jeschijahu 28:17

And I will make justice the line Before the advent of that king, I will bring decrees upon you to end the transgressors among you, and I will make the judgment of chastening to the line; i.e., I will make the line the standard of chastening (var. the line of My standard, chastening), to bring upon you, and righteousness I will make that it should be the plummet that straightens the building of walls, i.e. that righteousness shall go before them and straighten their ways, that the transgressors shall be destroyed and the righteous shall remain.

To the line, to the plummet. The figure, taken from the line and plummet of the builders, is used because of the words I will lay the foundation. Some are of opinion that Hezekiah is meant by the tried stone.

and hail shall sweep away the shelter of lies That covering that you said, “For we have made lies our shelter,” I will bring hail and it shall sweep it away. (וְיָעָה) is an expression of sweeping. Comp. (I Kings 7:40) “the shovels (הַיָּעִים)” with which they scoop up the ashes from the stoves.
