The LORD [is] the portion of mine inheritance and of my cup: thou maintainest my lot.
Ver. 5. The Lord is the portion of mine inheritance] Therefore I have neither need nor mind to run a madding after dumb idols; for he is good original, universal, all sufficient, and satisfactory, proportionable, and fitting to my soul; so that, having him, I am abundantly provided for.
And of my cup] A phrase taken from those shares that every one had assigned unto him at feasts, Genesis 43:34 1 Samuel 1:4; 1 Samuel 9:23 : q.d. Thou art my meat and my drink, Lord, and I am very well content with my condition, be it better or worse. That which gives quiet in any portion, is, First, The favour and presence of God; Secondly, That it is from the hand of a Father; Thirdly, That it comes to us in the covenant of grace; Fourthly, That it is the purchase of Christ's blood; Fifthly, That it is an answer of prayers, and a blessing from above on honest endeavours.
Thou maintainest my lot] Upholdest me in a good condition, who should otherwise soon lose and forego it, were it in mine own keeping. And here the psalmist useth four several words, all to the same sense, ad corroborandum, saith R. David.
