Commentary for Psalms 111:1

Hallelujah, I shall thank, etc. This psalm was based on the alphabet, one letter at the beginning of the verse and one in the middle of it, and so all of them [this psalm’s verses are] from “aleph” to “tav,” and so too is the second psalm. The first one speaks in praises of the Holy One, blessed be He, and the second one speaks in praise of a righteous, God-fearing person.
