Teaching Giving

Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh? (Isaiah 58:7)

Cast thy bread upon the waters: for thou shalt find it after many days. 2 Give a portion to seven, and also to eight; for thou knowest not what evil shall be upon the earth. (Ecclesiastes 11:1-2)

7 And hath not oppressed any, but hath restored to the debtor his pledge, hath spoiled none by violence, hath given his bread to the hungry, and hath covered the naked with a garment… 16 Neither hath oppressed any, hath not withholden the pledge, neither hath spoiled by violence, but hath given his bread to the hungry, and hath covered the naked with a garment (Ezekiel 18:7,16)

The verses in Ezekiel are taken from the context of God declaring that despite what some people may think, each person is only punished for his own sin. To oppress the poor and not act in the good way that God commands is actually sin. This raises the stakes.
Solomon writes in Ecclesiastes about the meaning of life. He starts off by explaining that life is meaningless without God. Our passage comes from the end of the book, where Solomon describes the things that are good to do in life. He pragmatically reasons that being generous is wise because hard times may come in the future and you need to have good friends. Many people will take advantage of you, these would not be the kind of wise investment Solomon is talking about. But if you pour out life, means (money) and energy into the church you will make friends that will not turn from you in hard times. Teach others to give selflessly to those who need it. Set an example by doing it yourself. Then when you or yours are in need there will be people ready to give.

Note on title: The title should be read as seen but it's interesting to note that in Koine Greek the word for teaching and giving is the same.
