2-kings 17:9

Fenced - Fortified; protected.

Did secretly those things - There was much hidden iniquity and private idolatry among them, as well as public and notorious crimes.

From the tower of the watchmen to the fenced city - That is, the idolatry was universal; every place was made a place for some idolatrous rite or act of worship; from the largest city to the smallest village, and from the public watchtower to the shepherd's cot.

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 2 Chronicles 26:10; 2 Chronicles 27:4.

17:9 Did secretly - This belongs, either, To their gross idolatries, and other abominable practices, which they were ashamed to own before others; or, to the worship of calves: and so the words are otherwise rendered; they covered things that were not right towards the Lord: they covered their idolatrous worship of the calves, with fair pretences of necessity, the two kingdoms being now divided, and at enmity; and of their honest intention of serving the true God, and retaining the substance of the Jewish religion. City - In all parts and places, both in cities, and in the country; yea, in the most uninhabited parts, where few or none dwell, beside the watchmen, who are left there in towers, to preserve the cattle and fruits of the earth, or to give notice of the approach of enemies.
