Exodus 23:18-19

23:18 “You must not offer ¹  the blood of my sacrifice with bread containing yeast; the fat of my festal sacrifice must not remain until morning. ²  23:19 The first of the firstfruits of your soil you must bring to the house of the Lord your God.

“You must not cook a young goat in its mother’s milk. ³ 

[23:18]  ¹ tn The verb is תִּזְבַּח (tizbbakh), an imperfect tense from the same root as the genitive that qualifies the accusative “blood”: “you will not sacrifice the blood of my sacrifice.” The verb means “to slaughter”; since one cannot slaughter blood, a more general translation is required here. But if the genitive is explained as “my blood-sacrifice” (a genitive of specification; like “the evil of your doings” in Isa 1:16), then a translation of sacrifice would work (U. Cassuto, Exodus, 304).
