Bible Study in Obsidian Kit (including the Bible in Markdown)

Tried to download a bible with the “BibleGateway-to-Obsidian Script”, however, when running the “bash bg2obs.sh” script it gave the next error:

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require': cannot load such file -- colorize (LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in require’
from bg2md.rb:77:in `’

How to make work?
