'Begin' in the Bible

Live lives which shall prove your change of heart; and do not begin to say to yourselves, 'We have Abraham as our forefather,' for I tell you that God can raise up descendants for Abraham from these stones.

But if that servant should say in his heart, 'My Master is a long time in coming,' and should begin to beat the menservants and the maids, and to eat and drink, drinking even to excess;

lest perhaps, when he has laid the foundation and is unable to finish, all who see it shall begin to jeer at him,

Then will they begin to say to the mountains, 'Fall on us;' and to the hills, 'Cover us.'
