When they had gone away, they (the gods), having bought and driven about the king (Soma), prepared the guest-offering for him. But the Asuras became aware of this also. The Idâ of that (offering) had been invoked, when they arrived; whence that sacrifice ends with the Idâ. The gods, espying the Asuras, snatched up the sacrifice, and began doing something else. They went away again, thinking, 'It is something else they are doing.'
