There are hundreds of sayings of our Mighty Lord Himself in the New Testament, which are apparently lacking in the original Hebrew Bible, but are in the Septuagint, Greek Translation, which apparently was what He considered scripture.
To cite the book of Sirach (knowing that many see "Yeshua" as Christ Himself without a clarifying statement) as if it were canon in the KJV is little short of deceptive. There is no book of Sirach in my 1611 KJV. You should have referenced it as "Ecclesiasticus."
It's an opinion reflecting yours.
I’m seeing Chapter 4 of Sirach/Ecclesiasticus in archaic language at

I would have to caution, that even demons can’t see into the heart (they judge external signs like poker players), but only the Lord knows the heart from the inside, closer than the marrow. (”And needed not that any should testify of man: for he knew what was in man.” - John 2:25)
Gold and Silver are refined in the fire, but the Lord tests the Hearts. - Proverbs 17:3
“(Yea a sword shall pearce thorow thy owne soule also) that the thoughts of many hearts may be reuealed.” - Luke 2:35, KJV 1611
When a person “doesn’t know what they think they know”, it used to be called rash judgment.
We call it “subjectifying ourselves while objectifying others”, but our mighty Lord whittled it down to the pithy:
Why do you see the speck in your brother’s eye, but ignore the 2 x 4 in your own? - Matthew 7: 3-5
