Deuteronomy 17

Deuteronomy 17:3

Richard Challoner: The host of heaven: That is, the stars.

Deuteronomy 17:6

Tertullian: “Two angels, however, appeared there.” For just so many honorary companions were required by the Word of God, which usually prescribes “two witnesses.” Moreover, the women, returning from the sepulcher and from this vision of the angels were foreseen by Isaiah, when he says, “Come, you women, who return from the vision”; that is, “come” to report the resurrection of the Lord. — AGAINST MARCION 4.43.2

Deuteronomy 17:7

1 Corinthians (5:9-13): I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth. Therefore put away from among yourselves that wicked person. [Deuteronomy 17:7]

Deuteronomy 17:8

Richard Challoner: [8] If thou perceive: Here we see what authority God was pleased to give to the church guides of the Old Testament, in deciding, without appeal, all controversies relating to the law; promising that they should not err therein; and surely he has not done less for the church guides of the New Testament.

Deuteronomy 17:11

Augustine of Hippo: Just as a person has to pick his way between fire and water so as to be neither burned nor drowned, so we should steer our way between the pinnacle of pride and the whirlpool of sloth, as it is written, “turning neither to the right nor to the left.” For there are some who, through fear of being carried up to the heights on the right, slip and are drowned on the left. Others … fear to be sucked in by the soft ease of sloth on the left and are ruined and destroyed by the ostentation of boasting on the other side, and [they] vanish into smoke and ashes. — LETTER 48

Deuteronomy 17:20

Basil of Caesarea: You are a wayfarer, like to him who prayed, “Direct my steps.” “Give heed to yourself” that you may swerve not from the path, that you decline neither to the right nor the left. Keep to the king’s highway. The architect should lay the firm foundation of faith which is Jesus Christ and let the builder look to his materials: not wood, nor hay nor stubble but gold, silver, precious stones. — HOMILY ON THE WORDS “GIVE HEED TO YOURSELF.”
