"It is because we have no bread." But Jesus, being aware of it, said to them, "Why do you reason because you have no bread? Do you not yet perceive nor understanding? Is your heart still hardened? Having eyes, do you not see? And having ears, do you not hear? And do you not remember? When I broke the five loaves for the five thousand, how many baskets full of fragments did you take up?" They said to Him, "Twelve." "Also, when I broke the seven for the four thousand, how many large baskets full of fragments did you take up?" And they said, "Seven." So He said to them, "How is it you do not understand?" - Mark 8:14-21
Here the disciples have just witnessed Jesus feeding four thousand and yet just a little while later they forget what He has done in performing a miracle of providing and multiplying. We see that as soon as they got in the boat they had already forgotten about the miracle, they had forgotten Jesus benefits. Jesus perceives them reasoning among them selves about this and asks how they could so easily forget, like in Psalm 103:2,5.
"Bless the LORD, O my soul, and forget not all His benefits....Who satisfies your mouth with good things, so that your youth is renewed like the eagle's." May we not be as quick to forget His benefits and doubt that He is the one Who satisfies our mouth with good things, that our strength might be renewed!
In Job 39:9 God is talking to Job and is in a sense stating His power and omnipotence and says, "Will the wild ox be willing to serve you? Will he bed by your manger?" Even there in Job God refers to or foretells of Jesus coming as a babe and laying in a manger among the animals.
