Luke 6:3

(ut sup.) And mark, that whenever the Lord speaks for His servants, (i. e. His disciples,) He brings forward servants, as for example David and the Priests; but when for Himself, He introduces His Father; as in that place, My Father worketh hitherto, and I work. (John 5:17.)

As if He said, Whereas the law of Moses expressly says, Give a righteous judgment, and ye shall not respect persons in judgment, (Deut. 1:16, 17.) how now do ye blame My disciples, who even to this day extol David as a saint and prophet, though he kept not the commandment of Moses?

Not only in the form of expression, but in His very practice and mode of action, did the Lord begin to absolve man from the observance of the old law. Hence it is said, And it came to pass that he went through the corn fields, &c. But the Lord proves the defenders of the law to be ignorant of what belongs to the law, bringing the example of David; as it follows, And Jesus answering said to them, Have ye not read so much as this, &c. But herein is a great mystery. For the field is the whole world, the corn is the abundant harvest of the saints in the seed of the human race, the ears of corn are the fruits of the Church, which the Apostles shaking off by their works fed upon, nourishing themselves with our increase, and by their mighty miracles, as it were out of the bodily husks, plucking forth the fruits of the mind to the light of faith. Now the Jews thought this unlawful on the Sabbath, but Christ by the gift of new grace represented hereby the rest of the law, the work of grace. Wonderfully has He called it the second-first sabbath, not the first-second, because that was loosed from the law which was first, and this is made first which was ordained second. It is therefore called the second sabbath according to number, the first according to the grace of the work. For that sabbath is better where there is no penalty, than that where there is a penalty prescribed. Or this perhaps was first in the foreknowledge of wisdom, and second in the sanction of the ordinance. Now in David escaping with his companions, there was a foreshadowing of Christ in the law, who with His Apostles escaped the prince of the world. But how was it that the Observer and Defender of the law Himself both eat the bread, and gave it to those that were with Him, which no one was allowed to eat but the priests, except that He might show by that figure that the priests' bread was to come over to the use of the people, or that we ought to imitate the priests' life, or that all the children of the Church are priests, for we are anointed into a holy priesthood, offering ourselves a spiritual sacrifice to God. (1 Pet. 2:5.) But if the sabbath was made for men, and the benefit of men required that a man when hungry (having been long without the fruits of the earth) should forsake the abstinence of the old fast, the law is surely not broken but fulfilled.

(cont. Hær. l. i. Hær. xxx. 32.) On the sabbath day then they were seen passing through the corn fields, and eating the corn, showing that the bonds of the sabbath were loosened, when the great Sabbath was come in Christ, Who made us to rest from the working of our iniquities.
