I said unto the LORD, Thou art my God: hear the voice of my supplications, O LORD.
David is the one speaking, declaring the Lord to be his own God in personal trust and belonging. That declaration is an expression of a real covenant relationship in which the speaker truly belongs to God. He joins that declaration to a direct plea for the Lord to hear the voice of his supplications. The plea is made on the ground of that personal relationship, because the Lord is his God. One who truly belongs to God may therefore humbly appeal to that covenant bond when asking to be heard.
