2 Kings 17:9

Literally, the words run thus - “And the children of Israel concealed (or ‘dissembled’) words which were not so concerning the Lord their God;” the true meaning of which probably is, the Israelites cloaked or covered their idolatry with the pretence that it was a worship of Yahweh: they glossed it over and dissembled toward God, instead of openly acknowledging their apostasy.

From the tower of the watchmen to the fenced city - This phrase was probably a proverbial expression for universality, meaning strictly; “alike in the most populous and in the most desolate regions.” “Towers of watchmen” were built for the protection of the flocks and herds which were pastured in waste and desert places 2Ch 26:10; 2 Chronicles 27:4.
