'Blessing' in the Bible

And Aaron, lifting up his hands to the people, gave them a blessing; and he came down from offering the sin-offering, and the burned offering, and the peace-offerings.

And Moses and Aaron went into the Tent of meeting, and came out and gave the people a blessing, and the glory of the Lord was seen by all the people.

Then I will command my blessing upon you in the sixth year, and it shall bring forth fruit for three years.

I will break your pride in your power, and I will make your sky like iron [giving no rain and blocking all prayers] and your ground like bronze [hard to plow and yielding no produce].
