答：第四条诫命是：「当记念安息日，守为圣日。六日要劳碌作你一切的工；但第七日是向耶和华你上帝当守的安息日；这一日你和你的儿女、仆婢、牲畜，并你城里寄居的客旅，无论何工都不可作，因为六日之内，耶和华造天、地、海和其中的万物，第七日便安息，所以耶和华赐福与安息日，定为圣日」（出20:8-11；申5:12-15）。

Q: Which is the fourth commandment?

A: The fourth commandment is, Remember the sabbath day, to keep it holy. Six days shall you labour, and do all thy work: but the seventh day is the sabbath of the Lord your God: in it you shall not do any work, you, nor your son, nor your daughter, your man-servant, nor your maid-servant, nor your cattle, nor your stranger that is within your gates: For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.
