Charles Ellicott Commentary Psalms 16:9

"Therefore my heart is glad, and my glory rejoiceth; My flesh also shall dwell in safety." — Psalms 16:9 (ASV)

Glory. —Hebrew, khabôd; but probably the poet wrote khabed, i.e., liver, or (compare “reins” above, and the common use of the word “bowels”) heart. The Septuagint's paraphrase is tongue. The passage was quoted this way in Acts 2:25. (Psalms 108:1.) “With the best member that I have” (Prayer Book).

Shall rest in hope. —This follows the Vulgate. The Septuagint also has “shall tabernacle in hope.” The true rendering, however, is shall rest in security. In “heart, soul, flesh,” the poet includes the whole living person. (Compare 1 Thessalonians 5:23.) The psalmist feels that the body must share with the soul the immunity from evil which is ensured by fellowship with God. Carried out to its full issue, the logical conclusion of this is the doctrine of immortality; but we must not see a conscious reference to it here.
