'Commandment' in the Bible

My son, keep your father's commandment, and don't forsake your mother's teaching.

For the commandment is a lamp, and the law is light. Reproofs of instruction are the way of life,

when he gave to the sea its boundary, that the waters should not violate his commandment, when he marked out the foundations of the earth;

He who keeps the commandment keeps his soul, but he who is contemptuous in his ways shall die.
