Exodus 21:3

If he should have come in alone, he shall also go forth alone; and if his wife should have gone in together with him, his wife also shall go out.

If he came in by himself, he shall go out by himself: if he were married, then his wife shall go out with him.

If he comes in by himself, he shall go out by himself. If he is married, then his wife shall go out with him.
