I just wanted to provide a quick explanation of the Torah Hebrew verbs.
Here is the image from Wikipedia article that will help you to understand them:
An excellent example that illustrates the difference would be the verb "baer"(בער) in Exodus 35:3. Please see my Shabbat article for complete explanation.
Please also note that the image above is in the shape of Menorah! This means that 7 branches of Tabernacle Menorah represented 7 conjugations (/binjanim/ - "constructions") just like cups on the branches represented 22 letters of the Torah Hebrew alphabet. Please see this post for illustration.
