'Apply' in the Bible

And take a bunch of hyssop and dip [it] into the blood that [is] in the basin and apply [some] of the blood that is in the basin to the lintel and the two doorposts. And you will not go out, anyone from the doorway of his house, until morning.

[in order] to incline your ear toward wisdom, [then] you shall apply your heart to understanding.

Incline your ear and hear the words of the wise; you shall apply your heart to my teaching.

Apply your heart to instruction, and your ear to sayings of knowledge.

And the man spoke to me, "Son of man, look with your eyes and listen with your ears and apply your heart to all that I [am] showing you, for you were brought here in order to show you [this]; tell all that you [are] seeing to the house of Israel."
