Starting to add tools to my bible study... (briefly on tithing)

I am starting an experiment in which I am planning on using Blogger to post my notes about whatever I am currently studying and as I endeavor to understand my own journey in life in Christ which I have committed to.
I tend to study with the only objective as to resolve my own issues which arise from time to time, but sometimes I find that I am not ready to defend what I have believed. But as I read the bible I am reminded that we are to be ready (1 Peter 3:15) to give an answer...
The project this night is to streamline my text by not having to copy the entire text into my blog. From now on I will be able to give a reference to a scripture and have it show the quote in a pop out balloon. I have it working now, but it doesn't seem to work with the mobile app version of the blog.
For the first new post am going to add some verses which I alluded to Sunday night in a Care Group meeting. I made a statement in Care Group last week that the absence of the teaching of tithing in the new testament with the exception of passages where the Jewish congregation was being spoken to was a "conspicuous absence" and in itself demonstrates that God was not extending this teaching to non-Jews.
Here are some examples. Note that God is directing these passages to the Jews. Also note that these references are at the time of Christ in the Gospels, or in the history of Israel, as in verses found in Hebrews. This is not an exhaustive study only a few verses. I may actually start a more in depth look at this as a doctrine someday.
