'Bless' in the Bible

Speak unto Aaron and unto his sons, saying, On this wise ye shall bless the children of Israel, saying unto them,

The LORD bless thee, and keep thee:

And they shall put my name upon the children of Israel; and I will bless them.

Behold, I have received commandment to bless: and he hath blessed; and I cannot reverse it.

And Balak said unto Balaam, Neither curse them at all, nor bless them at all.

And when Balaam saw that it pleased the LORD to bless Israel, he went not, as at other times, to seek for enchantments, but he set his face toward the wilderness.
