Example on page 149.
1Th 1:1 ¶ Paul, and Silvanus, and Timotheus, unto the church of the Thessalonians which is in God the Father and in the Lord Jesus Christ: Grace be unto you, and peace, from God our Father, and the Lord Jesus Christ.
The NASB and the NASB update omit " from God our Father, and the Lord Jesus Christ."
