Rashi knew the following conjugation rule: Each Biblical root has a grammatical form indicating the infinitive. The same infinitive grammatical form can, besides meaning the infinitive, also mean an ongoing intensive effort. Some sample verses and Rashis are cited below. Note how we incorporate the Rashi comment into the translation.

• Ex20-08 Be involved in Remembering the sabbath day, to keep it holy. [Rashi: Remember the Sabbath each day. For example if you see a good dish on the weekday, then purchase it for the Sabbath.]
• Ex13-03 And Moses said unto the people: 'Be involved in remembering this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand HaShem brought you out from this place; there shall no leavened bread be eaten. [Rashi: You should remember the exodus every day.]
• Dt01-16a And I charged your judges at that time, saying: 'Be involved in hearing cases between your brethren, and judge righteously between a man and his brother, and the stranger that is with him. [Rashi: Don't e.g. judge a case immediately but rather, in serious cases, wait at least one night before passing verdict (even if you have seen similar cases many times).]
• Dt27-01a And Moses and the elders of Israel commanded the people, saying: 'Be continuously involved in watching all the commandments which I command you this day. ... And it shall be on the day when ye shall pass over the Jordan ... that thou shalt set thee up great stones, .... And thou shalt write upon them all the words of this law, .... The Jews are commanded to perform continous acts of watching the Biblical commandments. They do this by creating a stone monument with a permanant record of the Torah law.
