Sirach 18:22

22 Let nothing hinder thee to pay thy vow in due time, and defer not until death to be justified.

Sirach 18:22 In-Context

20 Before judgment examine thyself, and in the day of visitation thou shalt find mercy.
21 Humble thyself before thou be sick, and in the time of sins shew repentance.
22 Let nothing hinder thee to pay thy vow in due time, and defer not until death to be justified.
23 Before thou prayest, prepare thyself; and be not as one that tempteth the Lord.
24 Think upon the wrath that shall be at the end, and the time of vengeance, when he shall turn away his face.
