Who said this quotation?

'I have found the one my soul loves'

I saw this quote on a past topic. I am looking to find where and the author said this quote. Is this from the Bible? poem?
Also, I saw this same quote with the word'whom':
'I have found the one whom my soul loves'


Anyone out there know?

Thanks!
