אַל־תַּ֭סֵּג גְּב֣וּל עוֹלָ֑ם וּבִשְׂדֵ֥י יְ֝תוֹמִ֗ים אַל־תָּבֹֽא׃
옛 지계석을 옮기지 말며 외로운 자식의 밭을 침범하지 말지어다
Tosefta Niddah
A man may not marry a pregnant woman [who was impregnated] by his fellow, or a nursing woman [who is nursing the child] of his fellow, on account of that which is said (Prov. 23:10), "Do not remove ancient boundary stones; Do not encroach upon the field of orphans" (JPS tr.).
