[Because of] his strength will I wait upon thee,.... Either because of the strength of Saul, who was stronger than David, he determined to wait upon the Lord for salvation and deliverance from him; or because of the strength of the Lord, which he expected from him, and therefore would wait upon him for it. The Septuagint and Vulgate Latin versions, and also the Chaldee paraphrase, render the words, "my strength will I keep for thee"; or "with thee". I ascribe all my strength unto thee; I expect every supply of it from thee, and put my trust and confidence in thee for it: so did Christ as man, and had strength from the Lord, according to his promise, Isaiah 50:7; and so every believer, Isaiah 14:24;
for God [is] my defence; or "my high refuge"; or "high tower" w; see Psalms 9:9; where he was defended and exalted, as is petitioned
Psalms 59:1; and was safe and secure from every enemy.
