For this my heart rejoiced Joy of the soul, gladness of the tongue, and quietness of all the whole body, do ensue upon sure hope and confidence; for unless men be quite past feeling, [1] they must needs be careful and sorrowful, and so, consequently, miserably tormented, so long as they feel themselves destitute of the help of God. But that sure trust which we repose in God doth not only deliver us from carefulness, [2] but doth also replenish our hearts with wonderful joy (and gladness.) That is the joy which Christ promised to his disciples should be full in them, and which he testified could not be taken from them, (John 16:22; 17:13.) He expresseth the greatness of the joy when he saith, That it cannot be kept in, but that it will break forth into the gladness of the tongue. [3] kvvd, doth signify, indeed, glory, but it is taken in that place, as in many others, for the tongue And so the Grecians have truly translated the same. The rest of the flesh doth signify the quietness of the whole man, which we have through the protection of God. Neither is this any let, because the faithful are continually out of quiet and tremble; for as in the midst of sorrows they do nevertheless rejoice; so there are no troubles so great that can break them of their rest. If any man object, that the peace of the faithful doth consist in the spirit, and that it is not in the flesh: I answer, that the faithful do rest in body; not that they are free from troubles, but because they believe that God careth for them wholly, and that not only their soul shall be safe through his protection, but their body also.

Footnotes

1 - "Stupeant," be stupid or stunned.

2 - "Anxietate," anxiety.

3 - "Quin erumpat in linguae exultationem," but will burst forth into the language of exultation.

Therefore - Peter ascribes these expressions to the Messiah. The reason why he would exult or rejoice was, that he would be preserved amidst the sorrows that were coming on him, and could look forward to the triumph that awaited him. Thus, Paul says Hebrews 12:2 that "Jesus"for the joy that was set before him," endured the cross, despising the shame," etc. Throughout the New Testament, the shame and sorrow of his sufferings were regarded as connected with his glory and his triumph, Luke 24:26; Philippians 2:6-9; Ephesians 1:20-21. In this our Saviour has left us an example that we should walk in his steps. The prospect of future glory and triumph should sustain us amidst all afflictions, and make us ready, like him, to lie down in even the corruptions of the grave.
Did my heart rejoice - In the Hebrew this is in the prescott tense, "my heart rejoices." The word "heart" here expresses "the person," and is the same as saying "I rejoice." The Hebrews used the different members to express the person. And thus we say, "every soul perished; the vessel had 40 hands; wise heads do not think so; hearts of steel will not flinch," etc. (Prof. Stuart on Psalm 16:1-11). The meaning is, because God is near me in time of calamity, and will support and deliver me, I will not be agitated or fear, but will exult in the prospect of the future, in view of the "joy that is set before me."
My tongue was glad - Hebrew, My glory or my honor exults. The word is used to denote "majesty, splendor, dignity, honor." It is also used to express the heart or soul, either because that is the chief source of man's dignity, or because the word is also expressive of the liver, regarded by the Hebrews as the seat of the affections, Genesis 49:6, "Unto their assembly, mine honor," that is, my soul, or myself, "be not thou united"; Psalm 57:8, "Awake up, my glory," etc.; Psalm 108:1, "I will singeven with my glory." This word the Septuagint translated "tongue." The Arabic and Latin Vulgate have also done the same. Why they thus use the word is not clear. It may be because the tongue, or the gift of speech, was what chiefly contributes to the honor of man, or distinguishes him from the brutal creation. The word "glory" is used expressly for "tongue" in Psalm 30:12; "To the end that my glory may sing praise to thee, and not be silent."
Moreover also - Truly; in addition to this.
My flesh - My body. See Acts 2:31; 1-Corinthians 5:5. It means here properly the body separate from the soul; the dead body.
Shall rest - Shall rest or repose in the grave, free from corruption.
In hope - In confident expectation of a resurrection. The Hebrew word rather expresses confidence than hope. The passage means, "My body will I commit to the grave, with a confident expectation of the future, that is, with a firm belief that it will not see corruption, but will be raised up." It thus expresses the feelings of the dying Messiah; the assured confidence which he had that his repose in the grave would not be long, and would certainly come to an end. The death of Christians is also in the New Testament represented as a sleep, and as repose Acts 7:60; 1-Corinthians 15:6, 1-Corinthians 15:18; 1-Thessalonians 4:13, 1-Thessalonians 4:15; 2-Peter 3:4; and they may also, after the example of their Lord, commit their bodies to the dust, in hope. They will lie in the grave under the assurance of a happy resurrection; and though their bodies, unlike his, will moulder to their native dust, yet this corruptible will put on incorruption, and this mortal will put on immorality, 1-Corinthians 15:53.

And my tongue was glad - In the Hebrew it is ויגל כבודי vaiyagel kebodi, "And my glory was glad:" but the evangelist follows the Septuagint, in reading και ηγαλλιασατο ἡ γλωσσα μου, what all the other Greek interpreters in the Hexapla translate δοξα μου, my glory. And what is to be understood by glory here! Why the soul, certainly, and not the tongue; and so some of the best critics interpret the place.

Therefore did my heart rejoice,.... Because that he had always the truth, faithfulness, and power of God in his view, and the presence and protection of God with him; and which are sufficient to make the hearts of his people, as well as of him, to rejoice:
and my tongue was glad: in the Hebrew text it is, "my glory"; and so the Syriac version renders it here; which Kimchi explains of the soul, because that is the glory of the body; but our apostle rightly interprets it of the tongue, which is so called, Psalm 30:12 and Psalm 57:8 and Psalm 108:1 because it is both the glory of man, for that being endowed with the faculty of speaking, gives him a glory above the brute creatures; and because it is that by which he glorifies God, by ascribing greatness to him, speaking of his marvellous works, and singing his praises, as Christ did, in the great congregation, among his apostles, a little before his death,
Moreover also my flesh shall rest in hope, or "safely"; meaning, that his body should lie quietly in the grave, as in its resting place from all toil and labour, pains and sorrows, and be secure from worms, or any corruption. Or this may be understood of his person being in a quiet, firm, and full hope of the resurrection of the dead, and of eternal life and glory.
