Isaiah 16:3

3 Take thou counsel, constrain thou counsel; set thou as night thy shadow in midday, hide thou them that flee, and betray thou not men of unsteadfast dwelling. (Take thou counsel, or advice, and constrain thou counsel; make thou thy shadow like the night at midday, hide thou them who flee away, and betray thou not those of unsteadfast dwelling.)

Isaiah 16:3 Meaning and Commentary

Isaiah 16:3

Take counsel, execute judgment
This refers either to what goes before, that they would take the counsel given, and do that which was just and right, by paying tribute to the king of Judah; or to what follows, that they would enter into a consultation, the king of Moab with his nobles, and resolve upon what was right, and do it, by protecting and harbouring the distressed Jews, who would flee unto them from the enemy: make thy shadow as the night in the midst of the noonday;
a time of the greatest heat, to which the Assyrian army, for its force and fury, and the mischief done by it, is compared: and the Moabites they are advised to make a shadow, as large and as strong as the dark night, that is, to protect the Jews in their distress, and to refresh and comfort them under it; see ( Isaiah 4:6 ) ( Isaiah 25:4 Isaiah 25:5 ) : hide the outcasts;
such as were driven out of their land through the fury and persecution of the enemy, receive and conceal, as Rahab did the spies: bewray not him that wandereth;
from his native place, as a bird from its nest, being forced to it; such an one, or as many as may be, in such a case, do not discover them where they are, or betray them, and deliver them up into the hands of their enemy.

Isaiah 16:3 In-Context

1 Lord, send thou out a lamb, (to) the lordly governor of [the] earth, from the stone of desert, to the hill of the daughter of Zion. (Lord, let them send out a lamb, from Sela in the wilderness, to the governor of the land, yea, to the hill of the daughter of Zion.)

2 And it shall be, as a fowl flying, and (as) birds flying away from the nest, so shall be the daughters of Moab, in the passing over of Arnon. (And it shall be, that like a flying bird, and like birds flying away from the nest, so shall be the daughters of Moab at the fords, or on the banks, of the Arnon River.)

3 Take thou counsel, constrain thou counsel; set thou as night thy shadow in midday, hide thou them that flee, and betray thou not men of unsteadfast dwelling. (Take thou counsel, or advice, and constrain thou counsel; make thou thy shadow like the night at midday, hide thou them who flee away, and betray thou not those of unsteadfast dwelling.)

4 My fleers-away shall dwell at thee. Moab, be thou the hiding place of them from the face of the destroyer. For why dust is ended, the wretched is wasted; he that defouled the land failed. (My fleers-away shall live with thee. Moab, be thou their hiding place from the face of the destroyer. For the destroyer is ended, the wretchful is wasted, he who defiled the land hath failed.)

5 And the king's seat shall be made ready in mercy, and he shall sit on it in truth, in the tabernacle of David, deeming, and seeking doom, and yielding swiftly that that is just. (And the king's throne shall be prepared in mercy, and he shall sit on it in truth, in the house of David, judging, and seeking justice, and swiftly yielding what is just, or what is right.)
