Psalms 10:16 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord is king To whom it belongs to protect his subjects. Therefore thou wilt save the humble, and punish the oppressors; for ever and ever Therefore his people's case is never desperate, seeing he ever lives and reigns to help them, and, therefore, he will help them in his time, sooner or later. The heathen Either, 1st, Those impious Israelites who oppressed David and other good men, whom, although they were reputed Israelites by themselves and others, yet he might call heathen for their heathenish opinions of God and his providence, and for their ungodly and unrighteous lives. Compare Isaiah 1:9, and Amos 9:7. Or, 2d, The Canaanites whom God, as king of the world, did expel or destroy, and gave their land to his people. By which great example David confirms his faith and hope for the future. Are perished out of his land Out of Canaan, which God calls his land, Leviticus 25:23, because he chose it for them, Ezekiel 20:6, and gave it to them, and fixed his presence and dwelling in it.
