4 how he entered the house of God , and they ate the consecrated bread , which was not lawful for him to eat nor for those with him, but for the priests alone ?

Matthew Henry's Commentary on Matthew 12:4

Commentary on Matthew 12:1-8

(Read Matthew 12:1-8)

Being in the corn-fields, the disciples began to pluck the ears of corn: the law of God allowed it, Deuteronomy 5:14. No law must be understood so as to contradict its own end. And as Christ is the Lord of the sabbath, it is fit the day and the work of it should be dedicated to him.
