'Who'll' in the Bible

Observe them carefully, because this will show your wisdom and discernment in the eyes of people who'll listen to all these decrees. Then they'll say: "Surely this great nation is a wise and discerning people.'

They aren't in the heavens, so you have to ask, "Who'll go up to the heavens for us and get it for us so we can hear it and act on it?'

And they aren't beyond the seas either, so you have to ask, "Who'll cross the sea and get it for us so we can hear it and act on it?'
