I own a concordance. It tells me where a word is found. If “Strong’s Concordance” includes other information, then it’s also a commentary.
The margin notes in the Geneva Bible are just a study guide. Nothing more. I've got a copy. I've read the notes. They are written by men, not God.
Pick up one or glance at one in a bookstore. Nothing untoward.
Actually, the one who really complained about the study notes was the King of England because the notes stressed religious independence from the monarchy.
A Strongs Conconrance has other info but it's not a commentary. Dr. Strong numbered every different word in the Bible and words are thus sorted and identified by their Strong's number. Since most lexicons use Strongs' numbers it is very easy to find and research the specific word in question as part of one's word studies. I prefer to use a reverse interlinear but a Strongs is still a powerful tool.
