JLPT1 G7 S3 F544
The relevant oracle bone form of this character shows a person + a hand reaching toward another person (compare 服) → *reach/extend* and press a hand on the back of a fleeing person → *overtake* → *amount to*; *equal*. By further extension are *and* and *as well as* (← equally), while *come to*, *exert* (upon) and *affect* derive from the original sense of exerting pressure with one's hand.
