'Second Man' in the Bible

and [then] the second man dislikes her and he writes her a letter of divorce and places [it] into her hand and sends her from his house, or if the second man dies who took her {to himself} as a wife,

Then Joram sent out a second horseman, who approached them and said, “Thus says the king: ‘Do you come in peace?’” Jehu replied, “What have you to do with peace? Rein in behind me.”

Then he said to another, 'And how much do you owe?' The second man replied, 'A hundred measures of wheat.' The manager said to him, 'Take your bill, and write eighty.'

The first man is of the earth, earthy: the second man is the Lord from heaven.
