How do I get Humanoid outside function(hit) ?

Guys, I want to get Humanoid with function(hit) but i want to use it outside of the function(hit). How do I do that?

Here is My Script

local Knife = script.Parent
local db = true

if db == true then
	Knife.Touched:Connect(function(hit)
		local Humanoid = hit.Parent:WaitForChild("Humanoid")	
	end)

	Humanoid:TakeDamage(1)
end

Try this.

local Knife = script.Parent
local db = true
local Humanoid

if db == true then
    Knife.Touched:Connect(function(hit)
        Humanoid = hit.Parent:WaitForChild("Humanoid")    
    end)

    Humanoid:TakeDamage(1)
end
