I have heard many different individuals cite I Corinthians 16:2, stating that the New Testament teaches that tithing is to be out of an individuals gross income.
However, my impression of the word εὐοδόω does not seem to allow this interpretation.
εὐοδόω apparently is a compound of εὖ (good, well) and ὁδός (way, road, journey), seemingly equivalent to "a prosperous journey."
This word appears 3 times in the Textus Receptus:
Rom 1:10 KJV 10 Making request, if by any means now at length I might have a prosperous journey by the will of God to come unto you.
1 Co 16:2 KJV 2 Upon the first [day] of the week let every one of you lay by him in store, as [God] hath prospered him, that there be no gatherings when I come.
3 Jo 1:2 KJV 2 Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.
My initial feeling was that this word has the following aspects:
- The outcome is unknown, but a positive one is hoped for.
- If, and only if, a positive outcome is achieved, certain events will follow.
To me, this implies profit, which I do not naturally associate with gross as much as net, considering that taxes and business expenses are not part of profit. My interpretation of I Corinthians 16:2 then becomes: "let each ... according to how much profit they have..."
Question: Is my evaluation of εὐοδόω correct?
