James 3:9-10
With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God's likeness. Our of the same mouth come praise and cursing. My brothers and sisters, this should not be.

Proverbs 4:1-7
1 Listen, my sons, to a father's instruction; pay attention and gain understanding. 2 I give you sound learning, so do not forsake my teaching. 3 For I too was a son to my father, still tender, and cherished by my mother. 4 Then he taught me, and he said to me, "Take hold of my words with all your heart; keep my commands, and you will live. 5 Get wisdom, get understanding; do not forget my words or turn away from them. 6 Do not forsake wisdom, and she will protect you; love her, and she will watch over you. 7 The beginning of wisdom is this: Get wisdom. Though it cost all you have, get understanding.
