Charles Ellicott Commentary Psalms 13:5

"But I have trusted in thy lovingkindness; My heart shall rejoice in thy salvation." — Psalms 13:5 (ASV)

But I. —Emphatic, but as for me. The most complete peace has taken the place of the despair with which the psalm opens. The rhythm of the Hebrew seems to express the restfulness of the thought. “It has a dying fall.” The Septuagint and Vulgate (compare the Prayer Book version) have an additional clause not found in any manuscript, Yea, I will praise the name of the Lord most high.
