'Sound' in the Bible

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

My son, do not let wisdom leave your sight. Carefully observe sound judgment and discernment,

I give you sound teaching, so do not abandon my instruction.

Counsel belongs to me, along with sound judgment. I am understanding. Power belongs to me.

Whoever isolates himself pursues selfish ends; he resists all sound advice.
