Someone may need to study and learn how the Peshitta differs from the traditional Hebrew Massoretic text and Greek Textus Receptus to aid in considering whether the English translations of it are accurate or not.
The Peshitta has the different reading "Titus" at Acts 18:7. Because of a likeness of ending, a line of Greek was omitted from some manuscripts at John 6:11 and this mistake can be found in the Peshitta Syriac Version. Thus, at John 6:11 the Lamsa Bible has Jesus distributing the bread to the multitude rather than to the disciples who distribute it to the multitude. At Luke 8:12, the Lamsa Bible and Murdock's New Testament have "the enemy" where the KJV has "the devil."
At John 1:18. Murdock's translation of the Syriac has "the only begotten God." Murdock's and Lamsa have "Isaiah the prophet" at Mark 1:2. Murdock's and Lamsa have "eagle" at Revelation 8:13 instead of "angel." They have “tree of life” instead of “book of life” at Revelation 22:19. Instead of “bishops” at Philippians 1:1, Murdock’s and Lamsa have “elders.” These two translations end 1 Corinthians 11:20 with “the day of our Lord” instead of “the Lord’s supper.” Murdock’s and Lamsa have “Barnabas” at Acts 13:13 where the KJV has “his company.” At John 1:28, Murdock’s and Lamsa have “Bethany” instead of “Bethabara.” Lamsa has “a Jew” instead of “the Jews” at John 3:25. Murdock’s has “Joseph of Ramath” at John 19:38 instead of “Joseph of Arimathaea.” Murdock’s has “Cephas” instead of “Peter” at Galatians 1:18. At Matthew 11:19, Lamsa has “justified by its works” where the KJV has “justified of her children.”
If compared to the KJV, the Peshitta has several omissions and additions. At Matthew 27:9, Murdock’s and Lamsa omit “Jeremy.” The Peshitta does not have "God" at Mark 12:32, and it does not have the last half of Matthew 27:35. Two phrases [“by them of old time”] are omitted at Matthew 5:27. At Matthew 25:13, a clause [“wherein the Son of man cometh”] is omitted. Another clause [“as they went to tell his disciples”] is missing at Matthew 28:9. Several words [“into the fire that never shall be quenched”] are omitted at Mark 9:45. At Mark 11:20, they omitted two phrases [“in the name of the Lord“]. The first half of Acts 9:6 is omitted. At Acts 28:16, several words [“delivered the prisoners to the captain of the guard”] are omitted. One commandment [“thou shalt not bear false witness”] is omitted at Romans 13:9. At Colossians 1:14, a phrase “through his blood”] is not found. Several words [“I am Alpha and Omega, the first and the last”] are missing at Revelation 1:11. In some verses, these two English translations of the Peshitta have additional words such as “the river” at Matthew 3:6, “it is I; be not afraid“ or “do not be afraid“ at Luke 24:36, “in Hebrew“ at John 20:16, “over Egypt” at Acts 7:18, “surnamed Agrippa“ at Acts 12:1, “to Antioch“ at Acts 12:25, “of the Lord” at Acts 14:25, “of Jesus“ at Acts 16:7, “in him“ at Romans 3:22, “the son of Nun” at Hebrews 4:8, and “by Jesus“ at Revelation 14:4. At Matthew 28:18, the Peshitta Syriac added the following words as translated in the Lamsa Bible: "just as my Father has sent me I am also sending you." At Acts 14:10, the Lamsa Bible has the phrase "in the name of our Lord Jesus Christ" which is not found there in the KJV.
