Albert Barnes' Bible Commentary
Psalms 125 - Introduction
This psalm is entitled merely “A Song of Degrees.” Its author, and the occasion on which it was composed, are unknown. The contents of the psalm accord well with the supposition that it may have been written after the return from the Babylonian captivity, and may have been designed to strengthen and comfort those who were engaged in rebuilding the city, and restoring the ancient worship, either against the Samaritans and those who opposed them Nehemiah 6:12, or against the lukewarmness of a part of the people themselves. There is nothing, however, so exclusively applicable to that time as to make it necessary to suppose that it was composed on that occasion. There is, indeed, evidence in the psalm Psalms 125:5, that there were some among the people who were disposed to turn away from the service of Yahweh, or who were perverse and rebellious; but such a state of things was not special to the time of the return from the captivity, nor was it special to the Jews, for it has occurred often; it exists still. The psalm is designed to encourage those who were disposed to trust in the Lord, by the assurance that they would be safe; that the blessing of God would be upon them; and that the church was firm and secure.
