But I know thy abode, and thy going out, and thy coming in, and thy rage against me.

Wesley's Notes

19:27 I know - Though thou dost not know me, yet I throughly know thee, and all thy designs and actions, all thy secret contrivances in the place of thy abode, in thy own kingdom and court; and the execution of thy designs abroad, what thou intendest in thy going out, and with what farther thoughts thou comest in, or returnest to thy own land.

abode: or, sitting

Matthew Henry's Concise Commentary

19:20-34 All Sennacherib's motions were under the Divine cognizance. God himself undertakes to defend the city; and that person, that place, cannot but be safe, which he undertakes to protect. The invasion of the Assyrians probably had prevented the land from being sown that year. The next is supposed to have been the sabbatical year, but the Lord engaged that the produce of the land should be sufficient for their support during those two years. As the performance of this promise was to be after the destruction of Sennacherib's army, it was a sign to Hezekiah's faith, assuring him of that present deliverance, as an earnest of the Lord's future care of the kingdom of Judah. This the Lord would perform, not for their righteousness, but his own glory. May our hearts be as good ground, that his word may strike root therein, and bring forth fruit in our lives.
