Sirach 26:22

22 An harlot shall be accounted as spittle; but a married woman is a tower against death to her husband.

Sirach 26:22 In-Context

20 When thou hast gotten a fruitful possession through all the field, sow it with thine own seed, trusting in the goodness of thy stock.
21 So thy race which thou leavest shall be magnified, having the confidence of their good descent.
22 An harlot shall be accounted as spittle; but a married woman is a tower against death to her husband.
23 A wicked woman is given as a portion to a wicked man: but a godly woman is given to him that feareth the Lord.
24 A dishonest woman contemneth shame: but an honest woman will reverence her husband.
