으러

To go and do something

Gives the purpose of going somewhere, and every single one of these eight lines has a verb of going, coming or heading out directly after it: heading off to withdraw cash, came to find her, came to eat meat, here to pick up our ID cards. That pairing is not optional — 으러 only works with movement. When the purpose belongs to some other kind of verb, the one you want is 으려고.
