Imamat 21:4

21:4 He must not defile himself as a husband among his people so as to profane himself. ¹ 

[21:4]  ¹ tn Heb “He shall not defile himself a husband in his peoples, to profane himself.” The meaning of the line is disputed, but it appears to prohibit a priest from burying any relative by marriage (as opposed to the blood relatives of vv. 2-3), including his wife (compare B. A. Levine, Leviticus [JPSTC], 142-43 with J. E. Hartley, Leviticus [WBC], 343, 348).
