Mark 8:1-

Mark 8
Jesus Feeds Four Thousand
1 About this time another large crowd had gathered, and the people ran out of food again. Jesus called his disciples and told them, 2 “I feel sorry for these people. They have been here with me for three days, and they have nothing left to eat. 3 If I send them home hungry, they will faint along the way. For some of them have come a long distance.”

4 His disciples replied, “How are we supposed to find enough food to feed them out here in the wilderness?”

5 Jesus asked, “How much bread do you have?”

“Seven loaves,” they replied.

6 So Jesus told all the people to sit down on the ground. Then he took the seven loaves, thanked God for them, and broke them into pieces. He gave them to his disciples, who distributed the bread to the crowd. 7 A few small fish were found, too, so Jesus also blessed these and told the disciples to distribute them.

8 They ate as much as they wanted. Afterward, the disciples picked up seven large baskets of leftover food. 9 There were about 4,000 people in the crowd that day, and Jesus sent them home after they had eaten. 10 Immediately after this, he got into a boat with his disciples and crossed over to the region of Dalmanutha.
Pharisees Demand a Miraculous Sign
11 When the Pharisees heard that Jesus had arrived, they came and started to argue with him. Testing him, they demanded that he show them a miraculous sign from heaven to prove his authority.

12 When he heard this, he sighed deeply in his spirit and said, “Why do these people keep demanding a miraculous sign? I tell you the truth, I will not give this generation any such sign.” 13 So he got back into the boat and left them, and he crossed to the other side of the lake.
Yeast of the Pharisees and Herod
14 But the disciples had forgotten to bring any food. They had only one loaf of bread with them in the boat. 15 As they were crossing the lake, Jesus warned them, “Watch out! Beware of the yeast of the Pharisees and of Herod.”

16 At this they began to argue with each other because they hadn’t brought any bread. 17 Jesus knew what they were saying, so he said, “Why are you arguing about having no bread? Don’t you know or understand even yet? Are your hearts too hard to take it in? 18 ‘You have eyes—can’t you see? You have ears—can’t you hear?’[a] Don’t you remember anything at all? 19 When I fed the 5,000 with five loaves of bread, how many baskets of leftovers did you pick up afterward?”

“Twelve,” they said.

20 “And when I fed the 4,000 with seven loaves, how many large baskets of leftovers did you pick up?”

“Seven,” they said.

21 “Don’t you understand yet?” he asked them.21

Helps: Jesus meets the need of the people following him by feeding them miraculously. This is the second such miracle yet the disciples are upset because they haven't enough food. Jesus wants them to see that He will provide for them but he does not want them to seek "proof" of his Lordship. Why do you believe that Jesus is the Son of God, Lord of Heaven and Earth, and your Savior? Or do you? What kind of proof did/do you need to believe? What are you looking for from Jesus?
