Thou preventest — i.e., comest to meet him. The word “prevent” is familiar in this sense in the English collect: “Prevent us, O Lord, in all our doings.” (Comp. Psalms 79:8; 1 Thessalonians 4:15.) The “crown “is by some identified with that won by David at Rabbah Moab. Others make it refer to a coronation. Ewald thinks of a birthday celebration. Probably no more is intended than a symbol of victory and rejoicing. Maidens were accustomed to meet a monarch returning in victory, and to offer a crown, or garland, which was a symbol of extraordinary rejoicing. (Comp. 1 Samuel 18:6; Psalms 68:11; Song of Solomon 3:11; Wis. 2:8; Jdt. 15:13; 3Ma. 7:16.)
