A valiant soldier should sharpen his sword to strike the enemy. He can be called neither valorous nor intelligent if he uses the sharpened sword on himself.
Similarly, sharpening one’s intellect by poring through the scriptural texts is in order to strike at the root of one’s own ignorance. Instead, using the sharpened intellect to win others by clever arguments is of no use at all.
