Charles H. Spurgeon on Psalms 85:1

The captivity of Jacob. All true believers are the sons of Jacob, and the seed of Abraham; as well as the believing Gentiles, who are the sons of Jacob according to the Spirit, as the believing Jews the sons of Jacob according to the flesh; and the Church of these true Jacobins and Israelites is the land of the Lord, and the captivity here mentioned is bondage under sin. In this captivity Satan is the gaoler, the flesh is our prison, ungodly lusts are the manacles, a bad conscience the tormentor, all of them against us; only Christ is Emmanuel, God with us; he turneth away the captivity of Jacob in forgiving all his offences, and in covering all his sins. Abraham Wright.
