'Apply' in the Bible

So as to turn your ear to wisdom, and apply your heart to understanding;

Turn your ear, and listen to the words of the wise. Apply your heart to my teaching.

Apply your heart to instruction, and your ears to the words of knowledge.

Son of man, I have broken the arm of Pharaoh king of Egypt; and behold, it has not been bound up, to apply [healing] medicines, to put a bandage to bind it, that it be strong to hold the sword.
