In the Psalm, the psalmist is praising Yahweh and recognizing his works of healing for the people. These healings were a part of Jesus’ own ministry here on earth, linking his Messiahship not to just being sent by Yahweh, but to being Yahweh himself in the flesh. This psalm tells us about Yahweh and thus tells us about Jesus and the praise and joy that he can illicit from us when we see him as king.
