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; to see Thy power and Thy glory, so as I have seen Thee in the sanctuary.
Because Thy lovingkindness is better than life, my lips shall praise Thee.  Thus will I bless Thee while I live: I will lift up my hands in Thy name.  My soul shall be satisfied as with marrow and fatness; and my mouth shall praise Thee with joyful lips:  When I remember Thee upon my bed, and meditate on Thee in the night watches.
Because Thou hast been my help, therefore in the shadow of Thy wings will I rejoice.  My soul followeth hard after Thee: Thy right hand upholdeth me.  But those that seek my soul, to destroy it, shall go into the lower parts of the earth.  They shall fall by the sword: they shall be a portion for foxes.  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.

Psalm 63:1-11

This is a Psalm of David while fleeing from king Saul, who was trying to kill him.   What can I learn from this Psalm?
