Leviticus 27:31
Context27:31 If a man redeems 4 part of his tithe, however, he must add one fifth to it. 5
1 tn Heb “which they may present from it an offering.” The plural active verb is sometimes best rendered in the passive (GKC 460 §144.f, g). Some medieval Hebrew
2 tn Heb “from it.” The masculine suffix “it” here is used for the feminine in the MT, but one medieval Hebrew
3 tn Heb “it and its substitute.” The referent (the original animal offered) has been specified in the translation for clarity.
4 tn Heb “And if redeeming [infinitive absolute] a man redeems [finite verb].” For the infinitive absolute used to highlight contrast rather than emphasis see GKC 343 §113.p.
5 tn Heb “its one fifth on it.”
