So think of musical time as a grid like a ruler. In this case I have 16 bars highlighted. If there were 60 seconds on a clock divided over 16 bars then every 4 bars would contain 15 seconds. Songs have a bpm that beats at a certain pace.

So 16 bars divide 4 with a line of poetry every 4 bars.

Drums have 4 beats to a bar.
I’m doing 4 bars (16 beats) for every line of poetry.
Or 16 bars (64 beats) for every verse or chorus.
