Psalms 119:94

I am thine - All that he had, and was, belonged to God. This is an expression of a fact, and of a purpose: a fact about which he had no doubt; a purpose ever to be the Lord’s. This is indicative of the real state of feeling in the heart of a pious man. He feels that he is the Lord’s; he has no other desire than to be his forever.

Save me - Deliver me from my enemies; from sin; from hell. As he belonged to God, he prayed that God would save and preserve his own.

For I have sought thy precepts - I feel assured or confident that this has been the aim and purpose of my life. On this ground I plead that thou wilt keep and preserve me. A man who feels assured that he is a friend of God has a right to appeal to him for protection, and he will not appeal to him in vain.
