Acts 26:5

Which knew me from the beginning, if they would testify, that after the most straitest sect of our religion I lived a Pharisee.

having known me from the first, if they are willing to testify, that after the strictest sect of our religion I lived a Pharisee.

having knowledge of me from the first, if they be willing to testify, that after the straitest sect of our religion I lived a Pharisee.

knowing me before from the first, (if they may be willing to testify,) that after the most exact sect of our worship, I lived a Pharisee;

They have known me for a long time and can testify, if they are willing, that I lived as a Pharisee, adhering to the strictest sect of our religion.
