'Begin' in the Bible

‘Now arise, continue on, and go through the valley of the Arnon. Look, I have handed over to you Sihon the Amorite, king of Heshbon, and his land. Begin! Take possession [of it] and fight with him in battle.

This day I will begin to put the dread and the fear of you on the peoples (pagans) under the whole heaven, who, when they hear the reports about you, will tremble and be in anguish because of you.’

The Lord said to me, ‘Look, I have begun to hand over to you Sihon and his land. Begin! Take possession [of it], so that you may possess his land.’

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