Numbers 6:24

יברכך [THE LORD] BLESS THEE — that thy property may increase (Sifrei Bamidbar 40). וישמרך AND MAY HE GUARD THEE — that no robbers come upon thee to take away thy property. For a human being who gives a present to his servant cannot guard him against everybody, and if a band of robbers attack him and take it away, what pleasure can he, then, derive from this present?! The Holy One, blessed be He, however, both gives and guards — against everybody (Midrash Tanchuma, Nasso 10). Many Midrashic interpretations are given of this verse in the Sifrei (Sifrei Bamidbar 40).

יְבָרֶכְךָ֥ יְהֹוָ֖ה וְיִשְׁמְרֶֽךָ׃ {ס}        

The Lord bless thee, and keep thee:
