Charles H. Spurgeon on Psalms 146:5

The God of Jacob. This verse aptly warrants us to apply to all believers all the illustrations of help and hope furnished by Jacob in his exile when none but God could help him. —Simon de Muis.

Verses 5-6. The God of Jacob...which wade heaven and earth, the sea, and all that therein is. It is a characteristic of these Psalms, to proclaim to all nations which worshipped idols, that "the God of Jacob", "the God of Zion", is the Creator and Governor of all things; and to make an appeal to all nations to turn to him. All these Psalms have a missionary character and an evangelical function. We may compare here the apostolic prayer at Jerusalem, after the descent of the Holy Ghost at Pentecost: "They lifted up their voices to God with one accord, and said, Lord, thou art God, that made heaven and earth, and the sea, and all that in them is" (where the words are the same as in the Septuagint in this place): "Who by the mouth of thy servant David hast said. Why do the heathen rage?" Ac 4:24-25 The office of these Psalms is to declare to the universe, that Jehovah, and he alone, is Elohim; and to invite all to worship him as such, by their oft repeated Hallelujah. —Christopher Wordsworth.
