Psalm 66:16

Come [and] hear, all ye that fear God
Who have a reverential affection for him, and by whom he is worshipped and served with reverence and godly fear; these have good things done for themselves, and will glorify God for what he does for others: these know the nature, worth, and value of the good things the Lord does for the souls of men, and hear them with pleasure and profit; when to tell them to others is casting pearl before swine, and giving that which is holy to dogs; and therefore only such as fear the Lord are called upon to come and hear what follows. Jarchi interprets this character of proselytes; see ( Acts 13:26 ) ;

and I will declare what he hath done for my soul:
not what he had done for God, or offered unto him, or suffered for his sake; nor what God had done for his body in the make and preservation of it; but what he had done for his soul, and the salvation of that: what God the Father had done in setting him apart for himself; in making a sure, well ordered, and everlasting covenant with him in Christ; in blessing him with all spiritual blessings in him; in providing for the redemption of his soul by him; in pardoning his sins, justifying his person, adopting him into his family, and regenerating, quickening, and sanctifying him: also what God the Son had done for him; in engaging to assume a true body and a reasonable soul on his account; and to make that soul an offering for his sin, and thereby obtain for him eternal redemption, even the salvation of his immortal soul: likewise what God the Spirit had done for him; in quickening and enlightening his soul; in implanting principles of grace and holiness in it; in showing Christ unto him, and bringing near his righteousness, and leading him to him for salvation and eternal life; in applying exceeding great and precious promises to him, and remembering to him such on which he had caused him to hope; in delivering him out of temptation and troubles, and in carrying on the work of his grace in him hitherto: these are things that are not to be concealed in a man's breast, but to be told to the church and people of God, to their joy and comfort, and to the glory of divine grace; see ( Mark 5:19 ) .
