This is a thread about Isaiah, thus thank you for posting that - as contextually it is the opposite; so lets now show where it is fake by context in the thread.
In Isaiah 52:10-14 the Spirit of Salvation is put into the Flesh of King David; in Isaiah 11:1-2, Isaiah 42:1, we're told the Spirit is put upon the Servant who is the Righteous Branch of Jesse.
The Source creates reality from the Word - like Code in a computer; therefore Yehoshua can not yield up his Spirit which was put on him by the Source, as the Source makes everything (Isaiah 45:7).
'Know thou that when the Son of Man yielded up His breath to God, the whole creation wept with a great weeping. By sacrificing Himself, however, a fresh capacity was infused into all created things.'
This teaching from Baha'u'llah is the same Pharisaic Oral Tradition that Yeshua challenged in Mark 7:6-13, where he is citing Isaiah 29:9-14.
The Pharisee Oral Tradition since Babylon was - "The death of the righteous can atone for the sins of that Generation".
This allowed for corruption of the Torah, and Isaiah prophesied it; that the Blind Guides Isaiah 56:9-12 would mislead the flock, and turn all the sheep to their own way (Isaiah 53:6).
Isaiah 53:1 contextually links with Isaiah 28:9-19 to create the Bed of Adultery, as stated in Isaiah 28:20-21.
Where the Bed of Adultery is that the covenant with Death is Disannulled, before it was even thought about by Pauline Christianity.
Thus in Isaiah 28, when the Messiah comes explaining this precept upon precept; many won't listen before the Harvest is expected (Isaiah 28:11-13, Isaiah 28:22).
Basically Baha'u'llah is guilty of teaching people human sacrifice is acceptable, and the Bible has set a Snare (Isaiah 8:13-16), to catch out those not smart enough to study or know this intuitively.
The charge according to the Bible for the people who do these things according to Yeshua ('Vultures Gathering' - Luke 17:37), is they're all put in the Lake of Fire soon for being Ravenous Beings (Isaiah 34:15).
In my opinion.
