Matthew 25:3, 4
The foolish ones took their lamps but did not take along any extra oil. / But the wise ones took oil in flasks along with their lamps.
1 John 2:20, 27
You, however, have an anointing from the Holy One, and all of you know the truth. / And as for you, the anointing you received from Him remains in you, and you do not need anyone to teach you. But just as His true and genuine anointing teaches you about all things, so remain in Him as you have been taught.
