16:1-5 God tells sinners what they may do to prevent ruin; so he does to Moab. Let them send the tribute they formerly engaged to pay to Judah. Take it as good advice. Break off thy sins by righteousness, it may lengthen thy quiet. And this may be applied to the great gospel duty of submission to Christ. Send him the lamb, the best you have, yourselves a living sacrifice. When you come to God, the great Ruler, come in the name of the Lamb, the Lamb of God. Those who will not submit to Christ, shall be as a bird that wanders from her nest, which shall be snatched up by the next bird of prey. Those who will not yield to the fear of God, shall be made to yield to the fear of every thing else. He advises them to be kind to the seed of Israel. Those that expect to find favour when in trouble themselves, must show favour to those in trouble. What is here said concerning the throne of Hezekiah, also belongs, in a much higher sense, to the kingdom of Jesus Christ. Though by subjection to Him we may not enjoy worldly riches or honours, but may be exposed to poverty and contempt, we shall have peace of conscience and eternal life.
Isa 16:1-14. Continuation of the Prophecy as to Moab.
1. lamb—advice of the prophet to the Moabites who had fled southwards to Idumea, to send to the king of Judah the tribute of lambs, which they had formerly paid to Israel, but which they had given up (2Ki 3:4, 5). David probably imposed this tribute before the severance of Judah and Israel (2Sa 8:2). Therefore Moab is recommended to gain the favor and protection of Judah, by paying it to the Jewish king. Type of the need of submitting to Messiah (Ps 2:10-12; Ro 12:1).
from Sela to—rather, "from Petra through (literally, 'towards') the wilderness" [Maurer]. "Sela" means "a rock," Petra in Greek; the capital of Idumea and Arabia-Petræa; the dwellings are mostly hewn out of the rock. The country around was a vast common ("wilderness") or open pasturage, to which the Moabites had fled on the invasion from the west (Isa 15:7).
ruler of the land—namely, of Idumea, that is, the king of Judah; Amaziah had become master of Idumea and Sela (2Ki 14:7).
