Psalm 11:3

“For, lo, the sinners have bent the bow, they have prepared their arrows in the quiver, that they may in the obscure moon shoot at the upright in heart:” and from them let her turn her speech to the Lord and say, “For they have destroyed what Thou hast perfected” (ver. 3).” — the author cites it

“It follows, “In a heart and in a heart have they spoken evil.”” — editor's note: Ps. xi. 3.
