260. Thou, then, art chosen out of the whole number of the children of Israel, regarded as the firstfruits of the sacred offerings, set over the tabernacle so as to keep guard in the camp of holiness and faith, to which if a stranger approach, he shall surely die. Thou art placed there to watch over the ark of the covenant. All do not see the depths of the mysteries, for they are hid from the Levites, lest they should see who ought not to see, and they who cannot serve should take it up. Moses, indeed, saw the circumcision of the Spirit, but veiled it, so as to give circumcision only in an outward sign. He saw the unleavened bread of sincerity and truth; he saw the sufferings of the Lord, but he veiled the unleavened bread of truth in the material unleavened bread, he veiled the sufferings of the Lord in the sacrifice of a lamb or a calf. Good Levites have ever preserved the mystery entrusted to them under the protection of their own faith, and yet dost thou think little of what is entrusted to thee? First, thou shalt see the deep things of God, which needs wisdom. Next, thou must keep watch for the people; this requires justice. Thou must defend the camp and guard the tabernacle, which needs fortitude. Thou must show thyself continent and sober, and this needs temperance.
