Pause/Beat Function in Harlowe?

Hi, I'm a bit of a Twine noob, and was wondering if there is a way for a pause that lasts a specified amount of time can be added before more text appears. For example, a bit of text would appear, then a piece of code would allow a pause, and then more text would appear.

Is this possible, and if so, could you possibly give me the code for it?

Please let me know. Again, I am using Harlowe, on Mac OS X.
