For I fed you with milk, not with solid food [i.e., with basic fundamentals instead of more advanced teaching. See Heb. 5:12-13] because you were not able to absorb it,

What soldier ever served [in the army] and paid his own expenses? Who [ever] planted a grape orchard and did not get to eat some of the grapes it produced? Or, who [ever] tended a flock of goats and did not get to drink some of the milk?

Eat whatever is sold in the [public] meat markets, without asking any questions [about it] for [your] conscience' sake [i.e., do not inquire about the previous use of the food you buy, because you might discover something about it that would make you feel guilty of wrongdoing if you ate it].
