"And cleave to Him"—Deuteronomy 11:22.
We are instructed to mingle with the sages and interact with them whenever possible: join in their meals, do business with them, etc. This way we will learn from their ways and come to adopt their true beliefs.
The verse tells us to "cleave" to G‑d—but is it possible to cleave to G‑d who is likened to a consuming fire? Rather this means that we must cleave to Torah scholars.
