Ulangan 18:4

18:4 You must give them the best of your ¹  grain, new wine, and olive oil, as well as the best of your wool when you shear your flocks.

Ulangan 22:9

Illustrations of the Principle of Purity

22:9 You must not plant your vineyard with two kinds of seed; otherwise the entire yield, both of the seed you plant and the produce of the vineyard, will be defiled. ² 

[18:4]  ¹ tn Heb “the firstfruits of your…” (so NIV).

[22:9]  ² tn Heb “set apart.” The verb קָדַשׁ (qadash) in the Qal verbal stem (as here) has the idea of being holy or being treated with special care. Some take the meaning as “be off-limits, forfeited,” i.e., the total produce of the vineyard, both crops and grapes, have to be forfeited to the sanctuary (cf. Exod 29:37; 30:29; Lev 6:18, 27; Num 16:37-38; Hag 2:12).
