This painting was inspired by an excerpt in the Torah from Exodus 13:21. The passage speaks about how G-d led the people of Israel in a pillar of smoke by day and a pillar of fire by night. The painting is called "Follow Me" and is specifically about the pillar of fire, because of how the light helped them find their way in the dark.
The Hebrew words within the painting are:
וְלַיְלָה בְּעַמּוּד אֵשׁ, לְהָאִיר לָהֶם--לָלֶכֶת
v'laylah b'amood aish, l'ha'eer la'hem la'lechet
