GEN 15:13

13 And it was said to him, Know thou (a) before-knowing, that thy seed shall be [[a]] pilgrim four hundred years in a land not his own, and they shall make them subject to servage, and they shall torment them; (And the Lord said to him, Know thou a fore-knowing, that thy descendants shall be foreigners in a land not their own, and they shall make them subject to servitude, or to slavery, and they shall torment them for four hundred years;)
