Psalms 22:3

But thou [art] holy
Which may be considered either as an argument with his God, why he should hear and answer him, since he is holy, just, and faithful; he has promised, when any call upon him in a day of trouble, he will hear and answer them, and will be glorified by them; this Christ did, and therefore pleads his faithfulness to his promise: or rather a reason quieting him under divine desertion, and a sense of divine wrath, that God was righteous in all his ways, and holy in all his works; and that whereas he was the surety of his people, and had all their sins on him, it was perfectly agreeable to the holiness and justice of God to treat him in the manner he did; yea, it was done to declare his righteousness, that he might appear to be just, while he is the justifier of him that believes in him;

[O thou] that inhabitest the praises of Israel;
either the place where Israel offered the sacrifices of praise to God, the tabernacle or temple, the house of prayer and praise in which Jehovah dwelt: or the true Israel of God praising him, who are formed for himself, and called by his grace to show forth his praises; among whom he takes up his residence: or else the praises themselves; and so the phrase denotes God's gracious acceptance of them, and well pleasedness in them, signified by his inhabiting of them, and the frequent and constant ascription of them to him: and perhaps respect may be had chiefly to the praises of his people for providing such a Saviour for them, settling him in the fulness of time, and not sparing him, but delivering him up into the hands of justice and death for them; and for giving all things freely with him.
