'Son of Man' in the Bible

God is not a man who lies,or a son of man who changes His mind.Does He speak and not act,or promise and not fulfill?

The daughters of Zelophehad approached; Zelophehad was the son of Hepher, son of Gilead, son of Machir, son of Manasseh from the clans of Manasseh, the son of Joseph. These were the names of his daughters: Mahlah, Noah, Hoglah, Milcah, and Tirzah.

The descendants of Machir son of Manasseh went to Gilead, captured it, and drove out the Amorites who were there.

So Moses gave Gilead to the clan of Machir son of Manasseh, and they settled in it.

The family leaders from the clan of the descendants of Gilead—the son of Machir, son of Manasseh—who were from the clans of the sons of Joseph, approached and addressed Moses and the leaders who were over the Israelite families.
