Sirach 7:29

29 Fear the Lord with all thy soul, and reverence his priests.

Sirach 7:29 In-Context

27 Honour thy father with thy whole heart, and forget not the sorrows of thy mother.
28 Remember that thou wast begotten of them; and how canst thou recompense them the things that they have done for thee?
29 Fear the Lord with all thy soul, and reverence his priests.
30 Love him that made thee with all thy strength, and forsake not his ministers.
31 Fear the Lord, and honour the priest; and give him his portion, as it is commanded thee; the firstfruits, and the trespass offering, and the gift of the shoulders, and the sacrifice of sanctification, and the firstfruits of the holy things.
