Another Bible study question

It's been a while so I'll add another one I have a another question.

Malachi 3:10 says, “Bring ye all the tithes into the storehouse,” so that there would be food in God's house.

I don't know about the rest of you but I don't see money anywhere in this verse. This is the most commonly used verse about tithing in the Bible.

I have another question, if a preacher's job or purpose to preach and that's all that person does with no other income, how does this person get all that money? The house, cars and mabey even a boat? If your a Christian and your reading this which I sincerely hope you are, ask your preacher or pastor where does the money come from? Why is it needed every Sunday? You know what after that verse in the Bible why is it needed at all? Why not just pitch a tent up and preach for free? I'm not accusing anyone or anything, these are just questions not accusations. If you really want to know? Get all your friends to sign a petition asking the funds be displayed online in a group so everyone can see. Think about this I can almost guarantee if you asked your preacher or pastor the same question I'm asking you, this person will be offended or/and angry with you. So I beg you, ask you paster or preacher like I'm doing, I'm asking not accusing. What I'm asking and have been asking is with sincerity and most respectful way possible.

I love you all blass be.
