and that your lips may guard knowledge.

Proverbs 5:2 tn Heb “keep, protect, guard.”
Proverbs 5:2 sn This “discretion” is the same word in 1:4; it is wise, prudential consideration, careful planning, or the ability to devise plans with a view to the best way to carry them out. If that ability is retained then temptations to digress will not interfere.
