'Illustration' in the Bible

Then, when He noticed that the invited guests chose the best seats, He used this as an illustration and said to them,

Brethren, even a covenant made by a man--to borrow an illustration from daily life--when once formally sanctioned is not liable to be set aside or added to.

In illustration, brethren, of persecution patiently endured take the Prophets who have spoken as messengers from the Lord.
