Your hand will apprehend all Your enemies; Your right hand will seize those who hate You.
PSALM 21. This psalm contains a public and solemn thanksgiving for the prosperous and happy condition of the king. Its subject is almost the same with that of the preceding. “What was anticipated in the preceding psalm, the present poem appears to celebrate as having been achieved.” — Drake’s Harp of Judah.
Commenting on Psalm 21:1-13
"Thine hand shall find out all thine enemies: thy right hand shall find out those that hate thee." The destruction of the wicked is a fitting subject for joy to the friends of righteousness; hence here, and in most scriptural songs, it is noted with calm thanksgiving.
The psalmist, having taught his people to look back with joy and praise on what God had done for him and them, here teaches them to look forward with faith, and hope, and prayer, upon what God would further do for them: The king rejoices in God (Psa 21:1), and therefore we will be thankful; the king trusteth in God (Psa 21:7), therefore will we be encouraged.
