Devarim 19:8-10

Orthodox Jewish Bible

⁸ And if Hashem Eloheicha enlarge thy territory, as He hath sworn unto Avoteicha, and give thee kol ha’aretz which He promised to give unto Avoteicha;

⁹ If thou shalt be shomer over all these mitzvot to do them, which I command thee today, to love Hashem Eloheicha, and to walk ever in His ways; then shalt thou add three towns more for thee, beside these three;

¹⁰ That dahm naki (innocent blood) be not shed in thy land, which Hashem Eloheicha giveth thee for a nachalah, and so dahmim be upon thee.
