Mark 6:50-52

Stop being afraid.” [Ex 3:14] Then He got into the boat with them, and the wind ceased [as if exhausted by its own activity]; and they were completely overwhelmed, because they had not understood [the miracle of] the loaves [how it revealed the power and deity of Jesus]; but [in fact] their heart was hardened [being oblivious and indifferent to His amazing works].
