'Whereof' in the Bible

And Saul said unto his uncle, He told us plainly that the asses were found. But concerning the matter of the kingdom, whereof Samuel spake, he told him not.

Saul chose him three thousand men of Israel, whereof two thousand were with Saul in Michmash and in the mount of Beth-el, and a thousand were with Jonathan in Gibeah of Benjamin: and the rest of the people he sent every man to his tent.
