Malaquias 3

8 Will a man rob G-d?

Yet ye have robbed Me.

But ye say: Wherein have we robbed Thee?

In ma’aser (tithes) and terumah (offerings, contributions).*3:8 Ex 20:15

10 Bring ye kol hama’aser (all the tithes) into the Beis HaOtzar (House of the Treasury),

that there may be teref (food) in Mine Beis,*3:10 Hamikdash

and prove Me now herewith,

saith Hashem Tzva’os,

if I will not open you the windows of Shomayim,

and pour you out a brocha,

that there shall not be room enough to receive it.
