Here is some info on Jewish giving.
Tithing | My Jewish Learning It seems kind of complicated so I am glad that Christ has freed NT Christians from all the rules, but not the spirit of giving.
Following, I lay out a few tidbits surrounding giving in case something might help any reader. You are right that there can be a problem of people stirring up emotions, which of course can be quite legitimate, though in some cases not. I used to have to ask for donations as part of my job for a Christian non-profit. I can say with certainty that the preaching and or teaching gift can still operate when it comes to appeals for money. I will say that I felt I had compromised myself even and learned to back off from emotional, drawn out appeals. God loves a cheerful giver, not a coerced giver.
So, if they are laying on guilt, I would think twice about giving to them. If they are passionate and genuine, though and spell out clearly what the money is doing them that likely is a good place to give. Emotions can work for a believer, but they also can work against us. In reading a Charles Finney's book, "Love is not a Special Way of Feeling." The premise was to hear from God in spite of the emotions, that emotions in and of themselves can be morally neutral. Spiritually can include emotions but it has to go beyond that. (I may not agree with all his theology, but he makes some very good arguments in some of his work)
As I have been in developing countries I am not moved much by American appeals to give. Yes, the church building and ministers must be paid. Most churches have board meetings and you can get their info on how much and where the money goes. God recently blessed my church in the USA, with a new air conditioning system of over 100k and i am glad for that. In contrast though I have visited churches that are in hot climates with no air, where the only chairs are the cheap plastic ones.
So in giving, you have to find your lane. What has God given you to give and where does He want you to employ those resources? Besides this path which may include who and where God has brought you. I admit too that in the absence of any general leading, I try to give where God receives the most praise. I know people that will praise God all day for a hundred dollars. To me that is a mighty confirmation of their true need.
