With power You redeemed Your people, the sons of Jacob and Joseph. Selah
PSALM 77 Whoever was the penman of this psalm, the Holy Spirit seems, by his mouth, to have dictated a common form of prayer for the Church in her afflictions, that even under the most cruel persecutions the faithful might not fail to address their prayers to heaven.
Commenting on Psalm 77:1-20
Thou hast with thine arm redeemed thy people, the sons of Jacob and Joseph. All Israel, the two tribes of Joseph as well as those which sprang from the other sons of Jacob, were brought out of Egypt by a display of divine power, which is here ascribed not to the hand but to the arm of the Lord, because it was the fulness of his might.
The psalmist here recovers himself out of the great distress and plague he was in, and silences his own fears of God's casting off his people by the remembrance of the great things he had done for them formerly, which though he had in vain tried to quiet himself with (Psa 77:5, Psa 77:6) yet he tried again, and, upon this second trial, found it not in vain.
