Genesis 16:3

And Sarai Abram's wife took Hagar her maid the Egyptian, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife.

Ver. 3. After Abram had dwelt ten years.] The Rabbis tell us of a tradition that the Hebrews grounded from hence, that if a woman had no child in the first ten years, she might be held barren, and another wife taken. But this is like one of their ill glosses that marred so many good texts, and refuted by our Saviour the Lawgiver, who best understood his own meaning. Mat 5:31-32
