17 “Don’t you see that whatever enters the mouth goes into the stomach and then out of the body? 18 But the things that come out of a person’s mouth come from the heart, and these defile them. 19 For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander.
Proverbs 27:19 (NIV)
19 As water reflects the face, so one’s life reflects the heart.
1 Samuel 25:2-13 (NKJV)
2 Now there was a man in Maon whose business was in Carmel, and the man was very rich. He had three thousand sheep and a thousand goats. And he was shearing his sheep in Carmel. 3 The name of the man was Nabal, and the name of his wife Abigail. And she was a woman of good understanding and beautiful appearance; but the man was harsh and evil in his doings. He was of the house of Caleb. 4 When David heard in the wilderness that Nabal was shearing his sheep, 5 David sent ten young men; and David said to the young men, “Go up to Carmel, go to Nabal, and greet him in my name. 6 And thus you shall say to him who lives in prosperity: ‘Peace be to you, peace to your house, and peace to all that you have! 7 Now I have heard that you have shearers. Your shepherds were with us, and we did not hurt them, nor was there anything missing from them all the while they were in Carmel. 8 Ask your young men, and they will tell you. Therefore let my young men find favor in your eyes, for we come on a feast day. Please give whatever comes to your hand to your servants and to your son David.’ ” 9 So when David’s young men came, they spoke to Nabal according to all these words in the name of David, and waited. 10 Then Nabal answered David’s servants, and said, “Who is David, and who is the son of Jesse? There are many servants nowadays who break away each one from his master. 11 Shall I then take my bread and my water and my meat that I have killed for my shearers, and give it to men when I do not know where they are from?” 12 So David’s young men turned on their heels and went back; and they came and told him all these words. 13 Then David said to his men, “Every man gird on his sword.” So every man girded on his sword, and David also girded on his sword. And about four hundred men went with David, and two hundred stayed with the supplies.
Proverbs 10:4 (NIV)
4 Lazy hands make for poverty, but diligent hands bring wealth.
Proverbs 13:4 (NKJV)
4 The soul of a lazy man desires, and has nothing; But the soul of the diligent shall be made rich. Proverbs 12:24 (NKJV) 24 The hand of the diligent will rule, But the lazy man will be put to forced labor.
