Famous quotes containing the word commands:
“They went to him and woke him up, shouting, “Master, Master, we are perishing!” And he woke up and rebuked the wind and the raging waves; they ceased, and there was a calm. He said to them, “Where is your faith?” They were afraid and amazed, and said to one another, “Who then is this, that he commands even the winds and the water, and they obey him?””
—Bible: New Testament, Luke 8:24-25.
