Optical Illusion of Giving

In Parshas Terumah, Hashem tells Bnei Yisrael to "take" an offering for Him, though the word should have been "bring". And later the Nesi'im, who gave generously, have a letter missing from their name. What did they do wrong? A Gemara in Bava Basra about Rabbi Akiva and a skeptic who asks why Hashem doesn't just feed the poor himself gives the key. A father-in-law who supports his son-in-law's learning, while his wife asks how long it will go on, turns the question of who gives to whom upside down.
