I suspect that may be caused by Jude only having a single chapter.

I just noticed that there is a mistake on the jude passage. The response is missing the first verse.
“data”: [
{“bible”: “kjv”,
“passage”: “Jude”,
“chapter”: “Jude”,
“verse”: [
{
“number”: 0,
“text”: “1”
},
{
“number”: 0,
“text”: “”
},
{
“number”: 2,
“text”: “Mercy unto you, and peace, and love, be multiplied.”
},
{
“number”: 3,
“text”: “Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.”
},
