'Personal' in the Bible

“Kings will be your attendants,And their princesses your nurses.They will bow down to you with their faces to the earthAnd lick the dust of your feet;And you shall know [with an understanding based on personal experience] that I am the Lord;For they shall not be put to shame who wait and hope expectantly for Me.

“I will make those who oppress you consume their own flesh [in mutually destructive wars]And they will become drunk with their own blood as with sweet wine;And all mankind will know [with a knowledge grounded in personal experience] that I, the Lord, am your SaviorAnd your Redeemer, the Mighty One of Jacob.”
