Matthew Poole and continuators on Psalms 86:2

2 Preserve my soul, for I am holy : O thou my God , save thy servant that trusteth in thee .

Sanctified in some measure by thy Grace, and sincerely devoted to thy service. This, David speaks, not in a way of vain ostentation, but partly as a powerful argument to move God to hear his prayers, because he was one of that sort of men to whom God had engaged himself by his Promise and Covenant; and partly by way of just and necessary vindication of himself from the censures of his Enemies who represented him to the world, as a gross dissembler, and secretly a very wicked man; concerning which he here makes a solemn appeal to God, desiring audience and help from God, upon no other terms, than upon this supposition, that he was an holy man. Which, by the way, savoureth of no more arrogancy than when he elsewhere professeth his great love to and longing after God, his sincere obedience to all God's commands, and his hatred of every false way, and the like.

By thy Covenant, and my own choice.

Whereby thou seemest obliged in honour, and by promise to help me.
