Psalms 63:11

But the king shall rejoice - David shall come to the kingdom according to the promise of God. Or, if it refer to the captivity, the blood royal shall be preserved in and by Zerubbabel till the Messiah come, who shall be David's spiritual successor in the kingdom for ever.

That sweareth by him - It was customary to swear by the life of the king. The Egyptians swore by the life of Pharaoh; and Joseph conforms to this custom, as may be seen in the book of Genesis, Genesis 42:15, Genesis 42:16. See also 1 Samuel 1:26 : 1 Samuel 17:55, and Judith 11:7. But here it may refer to God. He is The King, and swearing by his name signifies binding themselves by his authority, acknowledging his supremacy, and devoting themselves to his glory and service alone.

The Chaldee has: "And the King shall rejoice במימר אלהא bemeymar Eloha, in the Word of God;" or, in the Word God; Meymar, Word, being taken here substantially, as in many other places, by the Targumist.

The mouth of them that speak lies - The mouth of those who acknowledge lying vanities, that worship false gods, shall be stopped. All false religions shall be destroyed by the prevalence of the truth. For he, Christ, shall reign till all his enemies are put under his feet. "Thy kingdom come, and hell's o'erpower: and to thy scepter all subdue." Amen and Amen.

But the king shall rejoice in God - This passage, as was remarked in the Introduction to the psalm, shows that this psalm could not have been composed in the time of Saul, since the title king was not then given to David. The use of the term here in the third person does not prove that the psalm could not have been written by David himself, for he may have spoken of himself simply as "the king," and all the more forcibly and properly as he was driven unjustly from his throne, and was now an exile, yet was still a king - the king. The title was his; the throne belonged to him, and not to Absalom who had driven him from it. It was not improper to allude to this fact in the manner in which it is referred to here, and to say that "the king" - the true, the real king - himself - should and would rejoice in God. He would find God to be his helper; and by God he would yet be restored to his throne.

Every one that sweareth by him shall glory - Everyone that sweareth to him, or maintains his oath of allegiance to him, shall be honored.

But the mouth of them that speak lies - All who have sworn falsely; all who have professed allegiance and have proved unfaithful; all those who, contrary to their oaths and their obligations, have been found in the rebellion. They shall not be permitted to exult or rejoice, but they shall be confounded and silenced. This expresses, therefore, the fullest confidence in God; the absolute belief of David that he would be again placed on his throne, and again permitted "to see the power and glory of God as" he had "seen it in the sanctuary" Psalm 63:2; the belief that he would be restored to prosperity, and that his enemies would be humbled and destroyed - So it will be with all who put their trust in God. There is certain joy and triumph for them, if not in this world, at least in the world to come.

63:11 The king - I who am already anointed king. Every one - That sweareth by the name of God, in truth, and judgment, and righteousness.Every sincere servant and worshipper of God. Shall glory - Shall rejoice in my deliverance.
