20 Srimad-Bhagavatam [Canto 8, Ch. 9
TRANSLATION

Rahu, the demon who causes eclipses of the sun and moon,
covered himself with the dress of a demigod and thus entered the
assembly of the demigods and drank nectar without being detected
by anyone, even by the Supreme Personality of Godhead. The
moon and the sun, however, because of permanent animosity
toward Rahu, understood the situation. Thus Rahu was detected.

PURPORT

The Supreme Personality of Godhead, Mohini-mirti, was able to
bewilder all the demons, but Rahu was so clever that he was not
bewildered. Rahu could understand that Mohini-mirti was cheating the
demons, and therefore he changed his dress, disguised himself as a
demigod, and sat down in the assembly of the demigods. Here one may
ask why the Supreme Personality of Godhead could not detect Rahu. The
reason is that the Lord wanted to show the effects of drinking nectar.
This will be revealed in the following verses. The moon and sun,
however, were always alert in regard to Rahu. Thus when Rahu entered
the assembly of the demigods, the moon and sun immediately detected
him, and then the Supreme Personality of Godhead also became aware of
him.
