'Begin' in the Bible

Do not refuse one another, unless perhaps it is just for a time and by mutual consent, so that you may devote yourselves to prayer and may then associate again; lest the Adversary begin to tempt you because of your deficiency in self-control.

For to begin with, I hear that when you come together as a church there are divisions among you, and in part I believe it.

Did the word of God begin with you, or did it come to you alone?
