This is NOT an exhaustive analysis of New Testament occurrances of the word that equates to hupeiko nor of extrabiblical use; nonetheless, it provides insight. This is all the referenced works in the Lexicon that appear directly with Hebrews 13:17.  

 

A few notes to help with reading this table:

• The first bullet item is Hebrews 13:17 containing hupeiko, (hupeikete specifically).
• The next two bullet items show the index of hupeiko (the second of the two shows where Hebrews 13:17 usage of ὑπείκετε [hupeikete] falls)
• The next bullet item (4th bullet) shows the definition of hupeiko
• The next bullet item (5th bullet) shows some voting about hupeiko
• The remaining bullet items are in pairs with the first being the English followed by the Greek for each of the extrabiblical occurrences of hupeiko
