Êxodo 31:17

17 Entre mim e os filhos de Israel é sinal para sempre; porque, em seis dias, o Senhor fez os céus e a terra e, no sétimo dia, descansou e tomou alento.`

17 It is a sign between me and the children of Israel for ever; because in six days the Lord made heaven and earth, and on the seventh day he took his rest and had pleasure in it.
