I will walk before the Lord; or, I shall walk, &c. This is either,
1. The psalmist's promise to God in requital of the favour last mentioned; I will therefore please God, as this phrase is used, Genesis 5:24, compared with Hebrews 11:5 Genesis 17:1. I will devote myself to the worship and service of God. Or,
2. His thankful acknowledgment of God's further favour. Though I be now banished from the place of thy presence and worship, yet I assure myself that I shall be restored to it, and shall spend my days in thy house and service, which is the one thing that I desired above all other things, Psalms 27:4. In the land of the living; amongst living men of this world. See Poole on "Psalms 27:13".
