'Begin' in the Bible

‘Arise, set out, and pass through the valley of Arnon. Look! I have given Sihon the Amorite, king of Heshbon, and his land into your hand; begin to take possession and contend with him in battle.

This day I will begin to put the dread and fear of you upon the peoples everywhere under the heavens, who, when they hear the report of you, will tremble and be in anguish because of you.’

The Lord said to me, ‘See, I have begun to deliver Sihon and his land over to you. Begin to occupy, that you may possess his land.’

“You shall count seven weeks for yourself; you shall begin to count seven weeks from the time you begin to put the sickle to the standing grain.

Who is the man that has planted a vineyard and has not begun to use its fruit? Let him depart and return to his house, otherwise he might die in the battle and another man would begin to use its fruit.
