'Perfect' in the Bible

and the flowers, and the lamps, and the tongs, of gold, and that perfect gold;

But the high places were not taken away out of Israel: nevertheless the heart of Asa was perfect all his days.

For the eyes of Yahweh run back and forth throughout the whole earth, to show himself strong in the behalf of them whose heart is perfect toward him. Herein you have done foolishly; for from henceforth you shall have wars."

He commanded them, saying, "Thus you shall do in the fear of Yahweh, faithfully, and with a perfect heart.

He did that which was right in the eyes of Yahweh, but not with a perfect heart.
