It means to look up the first mention or use of a word or typology to understand what it is you are trying to figure out correctly.
Ex. In Isa 49:8 "Thus saith the LORD, In an acceptable time have I heard thee, and in a day of salvation have I helped thee: And I will preserve thee, and give thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages;"
If "covenant" was something you wanted to know more about you would go to the first reference of the word, in...
Gen 6:18 "But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee."
You would then read Genesis chapter 6 to better understand how the word was used in context, and for an understanding of its usage and definition.
