'Sup' in the Bible

They shall come all for violence: their faces shall sup up as the east wind, and they shall gather the captivity as the sand.

And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink?

Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
