The word(s) "lessons" appears 150 time(s) in 149 verse(s) in Quran in Mohsin Khan translation.

(111) And (We destroyed also) Qarun (Korah), Fir'aun (Pharaoh), and Haman. And indeed Musa (Moses) came to them with clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), but they were arrogant in the land, yet they could not outstrip Us (escape Our punishment).

(112) And thus We have sent down the Book (i.e. this Qur'an) to you (O Muhammad صلى الله عليه وسلم), and those whom We gave the Scripture [the Taurat (Torah) and the Injeel (Gospel) aforetime] believe therein as also do some of these (who are present with you now like 'Abdullah bin Salam) and none but the disbelievers reject Our Ayat [(proofs, signs, verses, lessons, etc.,) and deny Our Oneness of Lordship and Our Oneness of worship and Our Oneness of Our Names and Qualities: i.e. Islamic Monotheism].

(113) Nay, but they, the clear Ayat [i.e. the description and the qualities of Prophet Muhammad صلى الله عليه وسلم written in the Taurat (Torah) and the Injeel (Gospel)] are preserved in the breasts of those who have been given knowledge (among the people of the Scriptures). And none but the Zalimun (polytheists and wrongdoers) deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(114) Then evil was the end of those who did evil, because they belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, Messengers, etc.) of Allah and made a mockery of them.

(115) And as for those who disbelieved and belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, Allah's Messengers, Resurrection, etc.), and the Meeting of the Hereafter, such shall be brought forth to the torment (in the Hell-fire).

(116) And you (O Muhammad صلى الله عليه وسلم) cannot guide the blind from their straying; you can make to hear only those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and have submitted to Allah in Islam (as Muslims).

(117) Only those believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), who, when they are reminded of them, fall down prostrate, and glorify the Praises of their Lord, and they are not proud.

(118) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, then turns aside therefrom? Verily, We shall exact retribution from the Mujrimun (criminals, disbelievers, polytheists, sinners).

(119) And We made from among them (Children of Israel), leaders, giving guidance under Our Command, when they were patient and used to believe with certainty in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(120) But those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to frustrate them - those, for them will be a severe painful torment.
