'Soul's' in the Bible

But I call on God as my soul’s witness, that it was to spare you [pain and discouragement] that I did not come again to Corinth—

And consider the patience of our Lord [His delay in judging and avenging wrongs] as salvation [that is, allowing time for more to be saved]; just as our beloved brother Paul also wrote to you according to the wisdom given to him [by God],

And the fruit of your soul's desire has gone from you, and all things delicate and shining have come to an end and will never again be seen.
