아브람의 아내 사래가 그 여종 애굽 사람 하갈을 가져 그 남편 아브람에게 첩으로 준 때는 아브람이 가나안 땅에 거한지 십 년 후이었더라
Tosefta Yevamot
One who marries a woman and remains with her for ten years, and she does not bear a child -- he [still] is not permitted to desist from [the commandment of "be fruitful and multiply"]. Rather, he goes out and gives her her ketubah lest he does not merit bearing children from her. And even though there is no proof of the matter, there is a hint of the matter, as it is said (Gen. 16:3), "at the end of ten years of Avram's settling in the land of Canaan."* The full verse reads, "And Sarai, the wife of Avram, took Hagar the Egyptian, her hand-maid at the end of ten years of Avram's settling in the land of Canaan, and gave her to Avram her husband as a wife for him." We learn from this that [the duration of] one's settling outside the Land [of Israel] is not included in the count.
