Deuteronomy 14:21

¹⁹ All flying insects are unclean for you; they may not be eaten.

²⁰ But you may eat any clean bird.

You are not to eat any carcass; you may give it to the foreigner residing within your gates, and he may eat it, or you may sell it to a foreigner. For you are a holy people belonging to the LORD your God. You must not cook a young goat in its mother’s milk.

²² You must be sure to set aside a tenth of all the produce brought forth each year from your fields.

²³ And you are to eat a tenth of your grain, new wine, and oil, and the firstborn of your herds and flocks, in the presence of the LORD your God at the place He will choose as a dwelling for His Name, so that you may learn to fear the LORD your God always.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
