Imamat 19:17

19:17 You must not hate your brother in your heart. You must surely reprove your fellow citizen so that you do not incur sin on account of him. ¹ 

Imamat 26:17

26:17 I will set my face against you. You will be struck down before your enemies, those who hate you will rule over you, and you will flee when there is no one pursuing you.

[19:17]  ¹ tn Heb “and you will not lift up on him sin.” The meaning of the line is somewhat obscure. It means either (1) that one should rebuke one’s neighbor when he sins lest one also becomes guilty, which is the way it is rendered here (see NIV, NRSV, NEB, JB; see also B. A. Levine, Leviticus [JPSTC], 129-30, and J. E. Hartley, Leviticus [WBC], 303, and the discussion on pp. 316-17), or (2) one may rebuke one’s neighbor without incurring sin just as long as he does not hate him in his heart (see the first part of the verse; cf. NASB, NAB).
