Charles Ellicott Commentary Psalms 132:3-5

"Surely I will not come into the tabernacle of my house, Nor go up into my bed; I will not give sleep to mine eyes, Or slumber to mine eyelids; Until I find out a place for Jehovah, A tabernacle for the Mighty One of Jacob." — Psalms 132:3-5 (ASV)

It is futile to search the historical accounts for this vow. It may be implied from 2 Samuel 7:2, and from the persistent purpose which David certainly cherished. The Septuagint and Vulgate give the vow in even greater detail, adding, and rest to my temples.
