Psalms 77:15

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. Ancient believers were in the constant habit of referring to the wonders of the Red Sea, and we also can unite with them, taking care to add the song of the Lamb to that of Moses, the servant of God. The comfort derivable from such a meditation is obvious and abundant, for he who brought up his people from the house of bondage will continue to redeem and deliver till we come into the promised rest. Selah. Here we have another pause preparatory to a final burst of song.

THIS Psalm describes the condition of a child of God under deep depression of spirit. He is much tried and bowed, and yet, at the same time, the saint at last gets the victory and, before the Psalm is over, the clouds are all removed from the sky and the heart rejoices in the sunlight of Divine Love. It is known to every Believer that the experience of a Christian is very variable. We are like our own strange weather in this land. South winds blow and all is warm and balmy, but in a few hours the north wind comes, or the cutting east wind—and soon the ground is covered with snow or hard white frost—and yet, perhaps, in another day or two there will be a storm! Some Believers have all spiritual weathers in a week. Being somewhat excitable, perhaps naturally, they readily take to themselves wings and mount aloft, but then as a high soar is often followed by a great fall, these very Believers are soon sighing and crying out of the very depths and half doubt whether they are the people of God at all! Nor must I say that is common to merely excitable people. Some of the very noblest heroes in the Christian army have had a very dark experience to go through. If you read the life of Martin Luther, of whom we may well say that never braver soldier fought beneath the banner of the Cross, you will find him the subject of the most terrible exercises. He was strong in his God, but he was very weak in himself—subject to ferocious temptations—temptations the like of which probably few of us have ever known because we are not men of his gigantic mold, and God does not allow trials to come upon us which were only suitable for him.

The son. of Jacob and Joseph - “The sons which Jacob begat and Joseph nourished.” says the Chaldee. The Israelites are properly called the sons of Joseph as well as of Jacob, seeing Ephraim and Manasseh, his sons, were taken into the number of the tribes. All the latter part of this Psalm refers to the deliverance of the Israelites from Egypt; and the psalmist uses this as an argument to excite the expectation of the captives. As God delivered our fathers from Egypt, so we may expect him to deliver us from Chaldea. It required his arm to do the former, and that arm is not shortened that it cannot save.

Thou hast with thine arm - That is, with strength or power, the arm being a symbol of strength. Exo 6:6; Exo 15:16; Psa 10:15. Redeemed thy people - Thou didst rescue or deliver them from Egyptian bondage. See the notes at Isa 43:3. The sons of Jacob and Joseph - The descendants of Jacob and Joseph. Jacob is mentioned because he was the ancestor of the twelve tribes; Joseph, because he was conspicuous or eminent among the sons of Jacob, and particularly because he acted so important a part in the affairs of Egypt, from whose dominion they were redeemed.
