Take your precautions. Caution and vigilance have the same meaning, like influence and effect. It is said: he took his caution, if he became alert and guarded against what is feared, as if he made caution his tool by which he protects himself and safeguards his soul. The meaning is: be cautious and guard yourselves against the enemy and do not allow him access to yourselves. So, flee when you flee to the enemy. Either in groups, scattered, one detachment after another, or all together, meaning united as one group. And do not falter, lest you throw yourselves into destruction. And it has been recited: 'flee' with the letter 'fa' pronounced with a vowel.
