New Defender's Study Bible Notes
40:1 waited patiently. Psalm 40 is a Messianic psalm, apparently recounting the innermost thoughts of the Lord Jesus on the cross. It is in this respect a corollary of Psalm 22. Christ suffered patiently the agonies of hell’s separation from God for the three long hours of darkness until the Father finally heard His cry. Then He could shout: “It is finished!” (John 19:30).
40:3 new song. Possibly this is the glorious “Song of the Lamb” (Revelation 15:3).
40:5 thy wonderful works. Innumerable as are the wonderful works of God in creation, they are exceeded by His marvelous plan of redemption and the future plans for His people yet to be revealed in the “exceeding riches of His grace” in the ages to come (Ephesians 2:7).
40:6 mine ears. The “opened ear” refers to the boring of a hole in the ear of a bond servant who, after becoming eligible for freedom, chooses instead to remain forever in the service of his master (see Exodus 21:6). This ritual symbolized the dedication of the servant to hear and obey only his master’s orders.
40:7 Lo, I come. That this psalm is a Messianic psalm is certain because of its application in Hebrews 10:5-10. It is prophetic of the thoughts in the heart of Christ, possibly as He hung on the cross, remembering how and why He had come into the world.
40:8 to do thy will. Just as the servant with the “opened ear,” Christ had come solely to do the will of the One who sent Him. It is significant that in quoting the psalm the author of Hebrews translated “mine ears hast thou opened” by “a body hast thou prepared me” (Hebrews 10:5). Not just the ear, but the whole body was to be made an offering for sins forever (Hebrews 10:10-12).
40:10 great congregation. See notes on Psalm 22:25; Hebrews 12:23.
40:12 innumerable evils. Surrounding Jesus on the cross was “the assembly of the wicked” (Psalm 22:16), and imposed on Him were all our “iniquities” or “punishments.”
40:12 my heart faileth me. Jesus died literally of a broken heart, as evidenced by the remarkable emergence of blood and water (see notes on John 19:34-35).
40:15 Aha, aha. See note on Psalm 35:21.
