'Unfamiliar' in the Bible

So he humbled you by making you hungry and then feeding you with unfamiliar manna. He did this to teach you that humankind cannot live by bread alone, but also by everything that comes from the Lord's mouth.

I will lead the blind along an unfamiliar way; I will guide them down paths they have never traveled. I will turn the darkness in front of them into light, and level out the rough ground. This is what I will do for them. I will not abandon them.

They are unfamiliar with peace; their deeds are unjust. They use deceitful methods, and whoever deals with them is unfamiliar with peace.
