Adam Clarke on Psalms 118:10

All nations compassed me about - This is by some supposed to relate to David, at the commencement of his reign, when all the neighboring Philistine nations endeavored to prevent him from establishing himself in the kingdom. Others suppose it may refer to the Samaritans, Idumeans, Ammonites, and others, who endeavored to prevent the Jews from rebuilding their city and their temple after their return from captivity in Babylon.

But in the name of the Lord will I destroy them - Dr. Kennicott renders אמילם amilam, "I shall disappoint them;" Bishop Horsley, "I cut them to pieces;" Mr. N. Berlin, repuli eas, "I have repelled them." "I will cut them off;" Chaldee. Ultus sum in eos, "I am avenged on them;" Vulgate. So the Septuagint.
