This and all the rest of the psalms that follow begin and end with Hallelujah, a word which puts much of God's praise into a little compass; for in it we praise him by his name Jah, the contraction of Jehovah. In this excellent psalm of praise, I. The psalmist engages himself to praise God (Psa 146:1, Psa 146:2). II. He engages others to trust in him, which is one necessary and acceptable way of praising him. 1. He shows why we should not trust in men (Psa 146:3, Psa 146:4). 2. Why we should trust in God (Psa 146:5), because of his power in the kingdom of nature (Psa 146:6), his dominion in the kingdom of providence (Psa 146:7), and his grace in the kingdom of the Messiah (Psa 146:8, Psa 146:9), that everlasting kingdom (Psa 146:10), to which many of the Jewish writers refer this psalm, and to which therefore we should have an eye, in the singing of it.
