Psalms 53:2

God looked down from heaven upon the children of men
In ( Psalms 14:2 ) , it is read, "the Lord" or "Jehovah"; in everything else there is an agreement in this verse; (See Gill on Psalms 14:2);

to see if there were [any] that did understand;
the Targum is, "that were understanding" in the law; it doubtless means understanding in divine and spiritual things;

that did seek God;
the above paraphrase is, "seeking doctrine from before the Lord".
