'Sound' in the Bible

He stores up sound wisdom for the upright;He is a shield to those who walk in integrity,

My son, let them not vanish from your sight;Keep sound wisdom and discretion,

For I give you sound teaching;Do not abandon my instruction.

“Counsel is mine and sound wisdom;I am understanding, power is mine.

He who separates himself seeks his own desire,He quarrels against all sound wisdom.
