'Commandments' in the Bible

What follows is a copy of the letter that King Artaxerxes gave to Ezra the priestly scribe. Ezra was a scribe in matters pertaining to the commandments of the Lord and his statutes over Israel:

"And now what are we able to say after this, our God? For we have forsaken your commandments

Shall we once again break your commandments and intermarry with these abominable peoples? Would you not be so angered by us that you would wipe us out, with no survivor or remnant?

Therefore let us enact a covenant with our God to send away all these women and their offspring, in keeping with your counsel, my lord, and that of those who respect the commandments of our God. And let it be done according to the law.
