The Tenth = Blessing

Gen. 28:20-22 "20 And Jacob vowed a vow, saying, If God will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on, 21 So that I come again to my father’s house in peace; then shall the LORD be my God: 22 And this stone, which I have set for a pillar, shall be God’s house: and of all that thou shalt give me I will surely give the tenth unto thee."

I believe that we are blessed by God everyday spiritually and materially, Jacob promised to give the tenth of all material blessings he would receive. Yet are we giving the tenth of all material blessings we are getting from God?

Malachi 3:8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings.  
 3:9 Ye [are] cursed with a curse: for ye have robbed me, [even] this whole nation.
If we are not we should, not just the tithe but also offerings.

yeah, that is true. Also, with our firstfruits. Prov. 3:9 "Honour the Lord with thy substance, and with the firstfruits of all thine increase."

A titthes  of what? an hour, an day, an week, an month?

Tithes of material blessings

what about this days?

We should give back what belongs to the Lord:

Malachi 3:8-10 "8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings. 9 Ye are cursed with a curse: for ye have robbed me, even this whole nation. 10 Bring ye all the tithes into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it."

I Still have a great deal of questions on this
