For this cause have I sent unto you Timotheus, who is my beloved son, and faithful in the Lord, who shall bring you into remembrance of my ways which be in Christ, as I teach every where in every church. (4:17)

Now if Timotheus come, see that he may be with you without fear: for he worketh the work of the Lord, as I also [do]. (16:10)

Let no man therefore despise him: but conduct him forth in peace, that he may come unto me: for I look for him with the brethren. (16:11)
