'Command' in the Bible

The tempter came and said to him, "If you are the Son of God, command these stones to become bread."

and said to him, "If you are the Son of God, throw yourself down. For it is written, 'He will command his angels concerning you' and 'with their hands they will lift you up, so that you will not strike your foot against a stone.'"

They said to him, "Why then did Moses command us to give a certificate of dismissal and to divorce her?"
