'Apply' in the Bible

For inquire, I pray thee, of the former age, And apply thyself to that which their fathers have searched out:

So as to incline thine ear unto wisdom, And apply thy heart to understanding;

Incline thine ear, and hear the words of the wise, And apply thy heart unto my knowledge.

Apply thy heart unto instruction, And thine ears to the words of knowledge.

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