Charles Ellicott Commentary Psalms 147:4

"He counteth the number of the stars; He calleth them all by [their] names." — Psalms 147:4 (ASV)

Stars. This proof of God’s power to help, by reference to the stars of heaven, which are beyond human ability to count, much less to name, but which the Almighty both counts and names, seems introduced rather abruptly, but the train of thought is clear. To assemble the dispersed of Israel, however numerous and scattered, was easy for the Ruler of the hosts of heaven. The original promise to Abraham was, of course, in the psalmist’s mind, but even more so Isaiah 40:26-28, from which the expression may have been taken. The dramatic phrase Lift your eyes on high and behold (Isaiah 40:26) supplies the necessary link for the abrupt introduction of this thought in the psalm.
