Jeremiah 49:31 does not declare the plan of the king of Babylon; but the words, "Arise, go ye up," etc., are once more the summons of the Lord, as is shown by the expression "saith Jahveh." The enemy is to march against a peaceful nation, dwelling securely, that has neither doors nor bars, i.e., does not live in cities surrounded by walls with gates and bars (cf. 1 Samuel 23:7; Deuteronomy 3:5), whose territory, therefore, is easily conquered. They dwell alone, apart from others, without connection and intercourse with other nations, from which they could obtain help and support. שׁליו, like זעיר, Job 36:2; Daniel 7:8, is a Chaldaizing form; elsewhere it is written שׁליו, Job 21:23, or שׁלו, Job 16:12. As to living securely, cf. Judges 18:7; Ezekiel 38:11; on living alone, 15:17. This last is elsewhere said only of Israel, Numbers 23:9; Deuteronomy 33:28. Their possessions will become the spoil of the enemy; God will scatter them to every wind (cf. Ezekiel 5:12; Ezekiel 12:14), and bring destruction on them from every side (on עבריו, cf. 1 Kings 5:4).
