Psalms 16:5 - Exposition

The Lord is the Portion of mine inheritance . God had said to Aaron, when he gave him no special inheritance in Canaan, "I am thy Part and thine Inherit-ante among the children of Israel" ( Numbers 18:20 ). David claims the same privilege. God is his "Portion," and he needs no other. And of my cup . A man's "cup" is, in Scripture, his lot or condition in life ( Psalms 11:6 ; Psalms 23:5 )—that which is given him to drink. David will have God only for his cup. Thou maintainest my lot; i.e. thou makest it firm and sure (comp. Psalms 30:6 , "In my prosperity I said, I shall never be moved").
