Larian Studios Forums Baldur's Gate III Baldur's Gate III - Help Tips & Tricks How do I get the Command spell as a Cleric?

This is probably a real newbie question but how do I get the Command Halt spell as a Cleric? I can see on https://baldursgate3.wiki.fextralife.com/Life+Domain that it's a level 1 spell and that I should be able to get it as a Life Domain Cleric, but I can't seem to get access to it. I've tried using Withers to change class and see what spells I can swap out, but not seeing Command for the life me of. I know it's probably something really simple I'm missing here. I'm using Shadowheart as one of my companions. Currently lvl 5.
