'Represent' in the Bible

And then the firstborn that she bears {shall represent his dead brother}, so that his name is not blotted out from Israel.

{As for me}, look, I [am] staying at Mizpah to represent [you] {before} the Chaldeans who come to us. But you, gather wine and summer fruit and oil, and put [them] in your vessels, and live in your towns that you have seized."
