'Perform' in the Bible

So the king hearkened not unto the people: for the cause was of God, that the LORD might perform his word, which he spake by the hand of Ahijah the Shilonite to Jeroboam the son of Nebat.

And the king stood in his place, and made a covenant before the LORD, to walk after the LORD, and to keep his commandments, and his testimonies, and his statutes, with all his heart, and with all his soul, to perform the words of the covenant which are written in this book.
