I counsel thee to keep the king's commandment, and that in regard of the oath of God.
The king's commandment - Yahweh, peculiarly the King of Israel in the theocracy: Ecclesiastes 8:3-4, prove it is not the earthly king who is meant (Ecclesiastes 5:8).
In regard of the oath of God - i:e., on account of the obligation imposed upon thee by the covenant which God made with Abraham and renewed with David; Solomon remembered Psalms 89:35, "I have sworn," etc. (Eccl. 8:36), and the penalties if David's children should forsake it (Eccl. 8:30-32), inflicted on Solomon himself; yet God not "utterly" forsaking him, (Eccl. 8:33-34; Deuteronomy 29:12-15, etc.)
