Albert Barnes Commentary Matthew 22:44

"The Lord said unto my Lord, Sit thou on my right hand, Till I put thine enemies underneath thy feet?" — Matthew 22:44 (ASV)

The Lord said, etc. This is the language of David. "Jehovah said to my Lord"—the Messiah—"Sit thou," etc. This was a prediction respecting the exaltation of Christ. To be raised to the right hand of a king was significant of favor, trust, and power. See Barnes on Matthew 20:21.

This was done respecting Christ, Mark 16:19; Acts 7:55; Romans 8:34; Ephesians 1:20; Hebrews 1:3; Hebrews 8:1; Hebrews 10:12.

Thine enemies thy footstool. A footstool is that which is under the feet when we are sitting—implying that we have it under subjection, or at our control. So he shall put all enemies under his feet—all his spiritual foes—all that rise up against him, Psalms 2:9, 12; Hebrews 10:13; 1 Corinthians 15:25.
