'Wait' in the Bible

So He went to her, and taking her hand He raised her to her feet: the fever left her, and she began to wait upon them.

For the Son of Man also did not come to be waited upon, but to wait on others, and to give His life as the redemption-price for a multitude of people."

and He said to them, "My heart is oppressed with anguish to the very point of death: wait here and keep awake."

Then a man ran to fill a sponge with sour wine, and he put it on the end of a cane and placed it to His lips, saying at the same time, "Wait! let us see whether Elijah will come and take him down."
