Ben Sira 15:9 In-Context

7 But people who are foolish or sinful will never even catch sight of Wisdom.

8 She will have nothing to do with conceited people; she never enters the mind of liars.

9 It is not appropriate for a sinner to sing hymns of praise, because his worship is insincere.

10 A hymn should be an expression of wisdom, inspired by the Lord himself.

11 Don't blame the Lord for your sin; the Lord does not cause what he hates.
