'Commandment' in the Bible

The statutes of the LORD are right, rejoicing the heart: the commandment of the LORD is pure, enlightening the eyes.

Be thou my strong habitation, whereunto I may continually resort: thou hast given commandment to save me; for thou art my rock and my fortress.

I have seen an end of all perfection: but thy commandment is exceeding broad.

He sendeth forth his commandment upon earth: his word runneth very swiftly.
