Parallel
Exodus 23:19
Swete's Septuagint · Berean Standard Bible
τὰς ἀπαρχὰς τῶν πρωτογενημάτων σου εἰσοίσεις εἰς τὸν οἶκον κυρίου τοῦ θεοῦ σου. οὐχ ἑψήσεις ἄρνα ἐν γάλακτι μητρὸς αὐτοῦ.
Bring the best of the firstfruits of your soil to the house of the LORD your God. You must not cook a young goat in its mother’s milk.
