Shophetim (Judges) 7:4

And יהוה said to Giḏ‛on, “The people are still too many. Bring them down to the water, and let Me prove them for you there. And it shall be, that of whom I say to you, ‘This one goes with you,’ let him go with you. And of whomever I say to you, ‘This one does not go with you,’ let him not go.”
