The name Janai in the Bible
Janai is mentioned only once in the Bible. All we know of him is that he is a Gadite living in Bashan (1 Chronicles 5:12).
Etymology of the name Janai
The name Janai comes from the enormous root group ענה ('ana):
The name Janai is any of the verbs ana made active: he will ana.
For a meaning of the name Janai, NOBSE Study Bible Name List reads Answerer. Alfred Jones (Dictionary of Old Testament Proper Names) makes a few very large assumptions. First he seems to find that God is the object and secondly Jones either assumes that where one person answers, somebody else must be listening, or that the person who answers must have been listening in the first place. Hence Jones reads The Lord Hears. But this is very far off par. A more proper interpretation would be He Answers.
