'Beginnings' in the Bible

And in the beginnings of your months ye shall present a burnt-offering to Jehovah: two young bullocks, and one ram, seven yearling lambs without blemish.

And I will multiply upon you man and beast, and they shall increase and bring forth fruit; and I will cause you to be inhabited as in your former times, yea, I will make it better than at your beginnings: and ye shall know that I am Jehovah.
