ה֗וֹי חֶ֚רֶב לַֽיהוָ֔ה עַד־אָ֖נָה לֹ֣א תִשְׁקֹ֑טִי הֵאָֽסְפִי֙ אַל־תַּעְרֵ֔ךְ הֵרָגְעִ֖י וָדֹֽמִּי׃
O thou sword of the LORD, how long will it be ere thou be quiet? Put up thyself into thy scabbard, rest, and be still.
Rashi on Jeremiah
sword of the Lord Which the Holy One, Blessed be He, brings to the world.
