Adam Clarke on Psalms 25:22

Redeems Israel, O God - The people are prayed for in the preceding verses as if one person; now he includes the whole, lest his own personal necessities should narrow his heart. and cause him to forget his fellow sufferers.

This verse stands out of the order of the Psalm; and does not appear to have formed a part of the alphabetical arrangement. It is a general prayer for the redemption of Israel from captivity; and may well be applied to those of the true Israel who are seeking for complete redemption from the power, the guilt, and the pollution of sin; and from all the troubles that spring from it. And let it be ever known, that God alone can redeem Israel.
