The second of the O Antiphons.
et dux domus Israel,
qui Moyse in igne flammae rubi apparuisti,
et ei in Sina legem dedisti:
veni ad redimendum nos in brachio extento.
And leader of the house of Israel,
Who appeared to Moses in the burning bush,
And on Sinai gave him the law,
Come to redeem us with outstretched arm.
