From the end of the earth will I cry unto thee, when my heart is overwhelmed: lead me to the rock that is higher than I.
The end — To which David was driven.
Lead me — Convey me into some high and secure fortress.
 I will abide in thy tabernacle for ever: I will trust in the covert of thy wings. /*Selah*/.
I will — I shall, I doubt not, be restored to the tabernacle, and worship thee there all my days.
 For thou, O God, hast heard my vows: thou hast given me the heritage of those that fear thy name.
Heritage — Thou hast granted me this singular mercy, to live in God's land, to enjoy his presence, and to worship in his tabernacle; which is the heritage that all that fear thee, prize and desire above all things.
 Thou wilt prolong the king's life: and his years as many generations.
Prolong — The years of my life and reign. Thus he speaks because his kingdom was not like Saul's, but established to him and his heirs; and because Christ, his son and heir, should actually, and in his own person possess the kingdom for ever.
 He shall abide before God for ever: O prepare mercy and truth, which may preserve him.
Abide — In the throne.
Before God — Living and ruling as in God's presence, serving God and worshipping him in his tabernacle.
Truth — Thy truth in giving me those mercies which thou hast promised, and thy mercy in giving me such further blessings as I needs.
