Ulangan 17:19

17:19 It must be with him constantly and he must read it as long as he lives, so that he may learn to revere the Lord his God and observe all the words of this law and these statutes and carry them out.

[7:5]  ¹ sn Sacred pillars. The Hebrew word (מַצֵּבֹת, matsevot) denotes a standing pillar, usually made of stone. Its purpose was to mark the presence of a shrine or altar thought to have been visited by deity. Though sometimes associated with pure worship of the Lord (Gen 28:18, 22; 31:13; 35:14; Exod 24:4), these pillars were usually associated with pagan cults and rituals (Exod 23:24; 34:13; Deut 12:3; 1 Kgs 14:23; 2 Kgs 17:10; Hos 3:4; 10:1; Jer 43:13).

[7:5]  ² sn Sacred Asherah poles. A leading deity of the Canaanite pantheon was Asherah, wife/sister of El and goddess of fertility. She was commonly worshiped at shrines in or near groves of evergreen trees, or, failing that, at places marked by wooden poles (Hebrew אֲשֵׁרִים [’asherim], as here). They were to be burned or cut down (Deut 12:3; 16:21; Judg 6:25, 28, 30; 2 Kgs 18:4).
