And this is the poem that I composed in Rome the capital:

I cry out and also call to men — youths together with elders, and even the aged.

Come to me and I will teach you the rules of the Holy Tongue, which have new aspects.

The foundations of grammar are indeed examined in my book, for those versed in law and judgment, wise and incisive.

Shall I not bring hidden matters to light within it, and disclose the treasured teachings of the commentators?

And into four chief treatises I will divide it, to clarify the required subjects.

Thirteen principles in each one — that is, fifty-two in total.

May my book, called HaBachur, bring joy to God and to mankind.
