44. The Lord said to my Lord. Here the Holy Spirit puts into the mouth of all the godly a song of triumph, that they may boldly defy Satan and all the ungodly, and mock at their rage, when they endeavor to drive Christ from his throne.

Verse 44. The Lord said, etc. This is the language of David. "Jehovah said unto 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. . This was done respecting Christ, . Thine enemies thy footstool.
