Charles H. Spurgeon on Psalms 120:7

I am for peace, etc. Jesus was a man of peace; he came into our world, and was worshipped at his nativity as the Prince of peace: there was universal peace throughout the world at the time of his birth; he lived to make peace "by the blood of his cross": he died to complete it. When he was going out of the world, he said to his disciples, "Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid": Joh 14:27. When he was risen from the dead, and made his first appearance to his disciples, he said unto them. "Peace be unto you": he is the peace maker: the Holy Ghost is the peace bringer: his gospel is the gospel of peace; it contains the peace of God which passeth all understanding. "I am for peace: but when I speak, they are for war". The bulk of the Jewish nation abhorred Christ, they were for putting him to death; to avenge which, the Lord brought the Roman army against them, and many of them were utterly destroyed. So David literally was for peace with Saul; yet, when opportunities made way for any negotiations, it was soon discovered Saul was for war, instead of peace, with him. May we see how this, which is the introductory psalm to those fourteen which follow, styled Songs of Degrees, hath a concern with our Lord Jesus Christ; and that David the son of Jesse was in many cases a type of him, and several of his enemies, sorrows, and griefs, forerunning figures of what would befall Messiah, and come upon him. Amen. —Samuel Eyles Pierce.
