How To Make A text label show different text?

So say there was A text label that said Hello students then i want to change the text with a script to say something like hi without adding another text label

you would want to do

local textLabel = script.Parent -- change it to your text label's full path
textLabel.Text = "Hello Students"
wait(5) -- change the wait value to how long u want to wait until showing the next text
textLabel.Text = "hi"
