'Commandments' in the Bible

Now this is the copy of the letter that the king Artaxerxes gave unto Ezra the priest, the scribe, even the scribe of the words of the commandments of Jehovah, and of his statutes to Israel:

And now, O our God, what shall we say after this? for we have forsaken thy commandments,

shall we again break thy commandments, and join in affinity with the peoples that do these abominations? wouldest not thou be angry with us till thou hadst consumed us, so that there should be no remnant, nor any to escape?
