furnish, provide, utensil

具 is composed of a variant of 鼎 (tripod cauldron) and a variant of 廾 (two hands). 廾 is a pictograph of two hands, so 具 depicts two hands lifting a tripod cauldron. The cauldron is a vessel for holding food, and lifting it signifies that the food is prepared and ready for guests to eat or for use in sacrificial rituals.
