Luke 2:35

Indeed, as a result of him the thoughts ¹  of many hearts will be revealed ²  – and a sword ³  will pierce your own soul as well!” ⁴ 

so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too."

and a sword will pierce even your own soul—to the end that thoughts from many hearts may be revealed."

Thus, the deepest thoughts of many hearts will be revealed. And a sword will pierce your very soul."

the pain of a sword-thrust through you--But the rejection will force honesty, as God reveals who they really are.

(And a sword will go through your heart;) so that the secret thoughts of men may come to light.

so that the inner thoughts of many will be revealed—and a sword will pierce your own soul too."

"(yes, a sword will pierce through your own soul also), that the thoughts of many hearts may be revealed."

Indeed, as a result of him the thoughts ¹  of many hearts will be revealed ²  – and a sword ³  will pierce your own soul as well!” ⁴ 

¹ tn Or “reasonings” (in a hostile sense). See G. Schrenk, TDNT 2:97.

² sn The remark the thoughts of many hearts will be revealed shows that how people respond to Jesus indicates where their hearts really are before God.

³ sn A sword refers to a very large, broad two-edged sword. The language is figurative, picturing great pain. Though it refers in part to the cross, it really includes the pain all of Jesus’ ministry will cause, including the next event in Luke 2:41-52 and extending to the opposition he faced throughout his ministry.

⁴ sn This remark looks to be parenthetical and addressed to Mary alone, not the nation. Many modern English translations transpose this to make it the final clause in Simeon’s utterance as above to make this clear.
