Proverbs 6:23
21 Bind them on your heart continually; fasten them around your neck. 22 When you walk about, they will guide you; when you lie down, they will watch over you; when you wake up, they will talk to you. 23 For the commandments are like a lamp; instruction is like a light, and rebukes of discipline are like the road leading to life 24 by keeping you from the evil woman, from the smooth tongue of the loose woman. 25 Do not lust in your heart for her beauty, and do not let her captivate you with her alluring eyes;
Matthew 5:14
12 Rejoice and be glad because your reward is great in heaven, for they persecuted the prophets before you in the same way. 13 “You are the salt of the earth. But if salt loses its flavor, how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people! 14 You are the light of the world. A city located on a hill cannot be hidden. 15 People do not light a lamp and put it under a basket but on a lampstand, and it gives light to all in the house. 16 In the same way, let your light shine before people, so that they can see your good deeds and give honor to your Father in heaven.

"... The light of life that his followers will have resonates with a passage in one of the Dead Sea Scrolls from Qumran (1QS 3:7) concerning God, as well as their self-description as “the sons of light.” This proclamation is in the context of the Sukkoth ceremony of light (m. Sukkah 5:1-4). Four huge menorah or candlesticks were placed in the Court of the Women, and it was said that the light was sufficient to illuminate all Jerusalem, calling to mind Zechariah 14:6. The Torah was described in terms of light for the world in Wisdom 18:4; Proverbs 6:23; Psalm 119:105; and Baruch 4:2, as well as in the rabbinic tradition ..."
