'Blessing' in the Bible

If you will not give ear and take it to heart, to give glory to my name, says the Lord of armies, then I will send the curse on you and will put a curse on your blessing: truly, even now I have put a curse on it, because you do not take it to heart.

Let your tenths come into the store-house so that there may be food in my house, and put me to the test by doing so, says the Lord of armies, and see if I do not make the windows of heaven open and send down such a blessing on you that there is no room for it.
