Psalms 16:9

“Therefore my heart is glad, etc.] Because he had the Lord always in view; he was at his right hand, for his support and assistance, as well as because of what is expressed in the next verses: this is the same with rejoicing in spirit, (<421021>Luke 10:21); it denotes an inward joy, and fulness of it, because of the Lord’s presence with him; (see <440228>Acts 2:28); and my glory rejoiceth; meaning either his soul, which is the most glorious and noble part of man, as Aben Ezra, Kimchi, and Ben Melech interpret it; or rather his tongue, as in (<440226>Acts 2:26); the faculty of speaking in man being what gives him a superior glory and excellency to other creatures, and is that whereby he…”

“glory--as heart (Psa 7:5), for self. In Act 2:26, after the Septuagint, "my tongue" as "the glory of the frame"--the instrument for praising God. flesh--If taken as opposed to soul (Psa 16:10), it may mean the body; otherwise, the whole person (compare Psa 63:1; Psa 84:2). rest in hope--(compare Margin).”

“Therefore my heart is glad - In view of this fact, that my confidence is in God alone, and my belief that he is my Protector and Friend. See the notes at Acts 2:26. And my glory rejoiceth - The Septuagint translate this, “my tongue,” and this translation is followed by Peter in his quotation of the passage in Acts 2:26. See the notes at that passage. The meaning here is, that whatever there was in him that was honorable, dignified, or glorious - all the faculties of his soul, as well as his heart - had occasion to rejoice in God. His whole nature - his undying soul - his exalted powers as he was made by God - all - all, found cause of exultation in the favor and friendship of God. The heart…”

“My glory - My tongue, which is a man's glory and privilege, above all other living creatures. Rejoiceth - Declares my inward joy. For this word signifies not so much eternal joy, as the outward demonstrations of it. My flesh - My body shall quietly rest in the grave. Shall rest - in confident assurance of its incorruption there, and of its resurrection to an immortal life: the flesh or body is in itself, but a dead lump of clay; yet hope is here ascribed to it figuratively, as it is to the brute creatures, Rom 8:19. Psalms 16:10”

“16:9-11 Knowing that not even death can separate him from the Lord strengthens the psalmist’s confidence. He fears a separation (see 13:3-4), but he remains confident of seeing the Lord (see 11:7).”

“my heart: Luk 10:21, Luk 10:22 my glory: Psa 30:12, Psa 57:8; Act 2:26; Jam 3:5-9 my flesh: Job 14:14, Job 14:15, Job 19:26, Job 19:27; Pro 14:32; Isa 26:19; Th1 4:13, Th1 4:14 rest in hope: Heb. dwell confidently Psalms 16:10”

“Thus then, as this concluding strophe, as it were like seven rays of light, affirms, he has the most blessed prospect before him, without any need to fear death. Because Jahve is thus near at hand to help him, his heart becomes joyful (שׂמח) and his glory, i.e., his soul (vid., on Psa 7:6) rejoices, the joy breaking forth in rejoicing, as the fut. consec. affirms. There is no passage of Scripture that so closely resembles this as Th1 5:23. לב is πνεῦμα (νοῦς), כבוד, ψυχή (vid., Psychol. S. 98; tr. p. 119), בּשׂר (according to its primary meaning, attrectabile, that which is frail), σῶμα. The ἀμέμπτως τηρηθῆναι which the apostle in the above passage desires for his readers in respect…”
