In the 75th psalm we have the Messiah speaking, except in verse 1 where the voice of believing Israel is heard giving thanks for the blessing they are assured is near. When the Messiah shall receive the assembly (or, when He shall reach the set time, —the exact reading is not clear) He will judge with equity. When everything on earth is broken up, He will be found to have established that which will abide. He will rule, as is said of Him in Isaiah 11.
If He shall reign in righteousness, the wicked shall not be passed by; the cup of the fury of God will be drunk by the nations (see Jeremiah 25).
Singing psalms to the God of Jacob (verse 9) brings in the thought of His faithfulness, for Jacob’s self-seeking course brought him much sorrow but he was a worshiper when nature’s energy was weakened (Hebrews 11:2121By faith Jacob, when he was a dying, blessed both the sons of Joseph; and worshipped, leaning upon the top of his staff. (Hebrews 11:21)). The horn (verse 10) is a figure of power.
