V.1-9 They have seven loaves. The number “7” is the complete number. Seven baskets are filled with the food left uneaten. The number fed was 4,000. The number “4” is that which speaks of “universal” going out in four directions North, East, West and South. God’s grace and love and provision go out worldwide. Another way it can be applied. Three represents heaven the Trinity, God the Father, Son and Holy Spirit. Four represents the earth as mentioned above. Seven is completion, when heaven and earth shall be in harmony, and Christ shall be the center of all (Eph. 1:10).
V.10-13 Israel had rejected Him, yet they persist in asking for a sign. It was useless to give proof to hearts which had decided not to believe. The trial was over. So He groaned in spirit with sorrow.
V.14-21 The disciples themselves were really blind, not willfully, but in fact. So here, the Lord has instruction for them. They had faith, but lacked understanding.
V.15 Pharisees = hypocrisy; Herod = worldliness.
