O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is;
Early — Heb. in the morning, Which implies the doing it with diligence and speed.
Thirsteth — For the enjoyment of thee in thy house and ordinances.
Flesh — The desire of my soul, is so vehement, that my very body feels the effects of it.
No water — In a land where I want the refreshing waters of the sanctuary.
 To see thy power and thy glory, so as I have seen thee in the sanctuary.
To see — To enjoy.
Power — The powerful and glorious effects of thy gracious presence.
 My soul shall be satisfied as with marrow and fatness; and my mouth shall praise thee with joyful lips:
Satisfied — When thou shalt fulfil my earnest desire of enjoying thee in the sanctuary.
 But those that seek my soul, to destroy it, shall go into the lower parts of the earth.
Shall go — Into the grave.
 They shall fall by the sword: they shall be a portion for foxes.
Foxes — Their carcases shall become a prey to wild and ravenous creatures.
 But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped.
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.
