15 And Jesus [repeatedly and expressly] charged and admonished them, saying, Look out; keep on your guard and beware of the leaven of the Pharisees and the leaven of Herod and the Herodians.
16 And they discussed it and reasoned with one another, It is because we have no bread.
17 And being aware [of it], Jesus said to them, Why are you reasoning and saying it is because you have no bread? Do you not yet discern or understand? Are your hearts in [a settled state of] hardness? [Isa. 6:9, 10; Jer. 5:21.]
18 Having eyes, do you not see [with them], and having ears, do you not hear and perceive and understand the sense of what is said? And do you not remember?
19 When I broke the five loaves for the 5,000, how many [small hand] baskets full of broken pieces did you take up? They said to Him, Twelve.
20 And [when I broke] the seven loaves for the 4,000, how many [large provision] baskets full of broken pieces did you take up? And they said to Him, Seven.
21 And He kept repeating, Do you not yet understand?
