Psalm 44:21

“For he who says, “O God, attend unto me,” and, “Look, O God,” and, “God knoweth the secrets of the heart plainly,” reveals the latent meaning of this word, viz. that Θεὸς is so called from θεασθαι.” — editor's note: Ps. xliv. 21.

“For He knoweth the secrets of the heart” (ver. 21).” — the author cites it

“And then she turned to the Lord Himself, saying, “Thou knowest the secrets of the heart,” and “all this is come upon us; yet have we not forgotten thee, neither have we dealt falsely in thy covenant; our heart is not turned back.”” — editor's note: Cf. Ps. xliv. 21.

“But if in the sight of God who sees all things and to whom the secrets of the heart lie open no man is just; then these heretics instead of adding to man’s dignity, clearly take away from God’s power.” — editor's note: Ps. xliv. 21; Heb. iv. 13.
