Not really.

NIV
34Then Simeon blessed them and said to Mary, his mother: "This child is destined to cause the falling and rising of many in Israel, and to be a sign that will be spoken against, 35so that the thoughts of many hearts will be revealed. And a sword will pierce your own soul too."
Nasb
34And Simeon blessed them and said to Mary (
A)His mother, "Behold, this Child is appointed for (
B)the fall and rise of many in Israel, and for a sign to be opposed-- 35and a sword will pierce even your own soul--to the end that thoughts from many hearts may be revealed."
The messege
33-35Jesus' father and mother were speechless with surprise at these words. Simeon went on to bless them, and said to Mary his mother,
This child marks both the failure and
the recovery of many in Israel,
A figure misunderstood and contradicted—
the pain of a sword-thrust through you—
But the rejection will force honesty,
as God reveals who they really are.
Amplified
34And Simeon blessed them and said to Mary His mother, Behold, this Child is appointed and destined for the fall and rising of many in Israel, and for a sign that is spoken against--(
A) 35And a sword will pierce through your own soul also--that the secret thoughts and purposes of many hearts may be brought out and disclosed.
NLT

KJV
