Parallel
Exodus 34:26
Swete's Septuagint · Berean Standard Bible
τὰ πρωτογενήματα τῆς γῆς σου θήσεις εἰς τὸν οἶκον κυρίου τοῦ θεοῦ σου. οὐ προσοίσεις ἄρνα ἐν γόλακτι 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.”
