'Heads' in the Bible

and the waters have been going and becoming lacking till the tenth month; in the tenth month, on the first of the month, appeared the heads of the mountains.

the land of Egypt is before thee; in the best of the land cause thy father and thy brethren to dwell -- they dwell in the land of Goshen, and if thou hast known, and there are among them men of ability, then thou hast set them heads over the cattle I have.'
