Tehillim 129:6-8

Orthodox Jewish Bible

⁶ Let them be as the khatzir (grass) upon the housetops, which withereth before it groweth up;

⁷ With it the kotzer (reaper) filleth not his yad; nor he that gathereth sheaves, his bosom.

⁸ Neither do they which go by say, Birkat Hashem be upon you; we bless you b’Shem Hashem.
