1QS 3
Community RuleFor it is through the spirit of true counsel concerning the ways of man that all his sins shall be expiated, that he may contemplate the light of life. He shall be cleansed from all his sins by the spirit of holiness uniting him to His truth, and his iniquity shall be expiated by the spirit of uprightness and humility. And when his flesh is sprinkled with purifying water and sanctified by cleansing water, it shall be made clean by the humble submission of his soul to all the precepts of God. Let him then order his steps {to walk} perfectly in all the ways commanded by God concerning the times appointed for him, straying neither to the right nor to the left and transgressing none of His words, and he shall be accepted by virtue of a pleasing atonement before God and it shall be to him a Covenant of the everlasting Community.
John 8:12
10 Jesus stood up straight and said to her, “Woman, where are they? Did no one condemn you?” 11 She replied, “No one, Lord.” And Jesus said, “I do not condemn you either. Go, and from now on do not sin any more.”]] 12 Then Jesus spoke out again, “I am the light of the world! The one who follows me will never walk in darkness but will have the light of life.” 13 So the Pharisees objected, “You testify about yourself; your testimony is not true!” 14 Jesus answered, “Even if I testify about myself, my testimony is true because I know where I came from and where I am going. But you people do not know where I came from or where I am going. 15 You people judge by outward appearances; I do not judge anyone.
Notes and References
"... Of the other “shared literary expressions” listed by Charlesworth, “A Critical Comparison,”, only three deserve mention as arguably instances of the light / darkness imagery - (1) “to walk in the paths of darkness” (1QS 3:21; 4:11) and “to walk in darkness” (John 8:12; 12-35; compare 1 John 1:6; 2-11); (2) “the light of life” (1QS 3:7; John 8:12); (3) “blindness of eyes” (1QS 4:11) and “the eyes of the blind” (John 10:21; compare John 9). On these the following comments should be made- (1) Both expressions are biblical- “to walk in the paths of darkness” (Proverbs 2-13), “to walk in darkness” (Psalm 82:5; Ecclesiastes 2:14; Isaiah 9:2). 1QS uses the former twice (1QS 3:21; 4:11) and the latter once (1QS 11:10), whereas John uses only the latter (John 8:12; 12:35; compare 1 John 1:6; 2:11) ..."
