Sir 4:12 Wisdom inspireth life into her children, and protecteth them that seek after her, and will go before them in the way of justice.
Sir 4:13 And he that loveth her, loveth life: and they that watch for her, shall embrace her sweetness.
Sir 4:14 They that hold her fast, shall inherit life: and whithersoever she entereth, God will give a blessing.
Sir 4:15 They that serve her, shall be servants to the holy one: and God loveth them that love her.
Sir 4:16 He that hearkeneth to her, shall judge nations: and he that looketh upon her, shall remain secure.
Sir 4:17 If he trust to her, he shall inherit her, and his generation shall be in assurance.
Sir 4:18 For she walketh with him in temptation, and at the first she chooseth him.
Sir 4:19 She will bring upon him fear and dread and trial: and she will scourge him with the affliction of her discipline, till she try him by her laws, and trust his soul.
Sir 4:20 Then she will strengthen him, and make a straight way to him, and give him joy,
Sir 4:21 And will disclose her secrets to him, and will heap upon him treasures of knowledge and understanding of justice.
Sir 4:22 But if he go astray, she will forsake him, and deliver him into the hands of his enemy.
Wisdom is an important topic in both Proverbs and Sirach. God's wisdom is the only wisdom that matters, and the wisdom we should seek. Our own wisdom must come from God to be true and useful, and if we rely on our own understanding without God's wisdom and guidance it will be disastrous. We see that happen all the time in the history of Israel, and we see it now as our world logics our way into murder and other sin on the grounds of reason. That's how we end up with the sin of abortion, among others.
