"You shall not make for yourself an idol, or any likeness of what is in heaven above or on the earth beneath or in the water under the earth. You shall not worship them or serve them; for I, the LORD your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me, but showing lovingkindness to thousands, to those who love Me and keep My commandments." (Exodus 20:4-6) The literal commandment is that we should not serve idols.
"Speak to the sons of Israel, and tell them that they shall make for themselves tassels on the corners of their garments throughout their generations, and that they shall put on the tassel of each corner a cord of blue. It shall be a tassel for you to look at and remember all the commandments of the LORD, so as to do them and not follow after your own heart and your own eyes, after which you played the harlot, so that you may remember to do all My commandments and be holy to your God." (Numbers 15:38-40)
The literal commandment is not to follow after our own hearts and our own eyes (which lead us into idolatry).
"You shall teach them diligently to your sons and shall talk of them when you sit in your house and when you walk by the way and when you lie down and when you rise up." (Deuteronomy 6:7)
The literal commandment is that we should teach G-d's commandments diligently to our children. However, in order to be able to teach the commandments we have to learn them first.
"You shall not go about as a slanderer among your people, and you are not to act against the life of your neighbor; I am the LORD." (Leviticus 19:16)
The literal commandment is that we should not be a slanderer. The Hebrew word which is translated as "slanderer" [rakil] comes from a word that means "to travel" and connotes "traveling about spreading gossip or slander".
