John Gill Commentary Luke 8:49

"While he yet spake, there cometh one from the ruler of the synagogue`s [house], saying, Thy daughter is dead; trouble not the Teacher." — Luke 8:49 (ASV)

While he yet spoke
The above words to the woman;

there cometh one :
Mark suggests there were more than one, (Mark 5:35) , (See Gill on Mark 5:35) and the Persic version here reads, "some of the ruler's family came"; that is, to him, who was now with Jesus: from the ruler of the synagogue's house; so the word "house" is supplied by the Syriac and Ethiopic versions; otherwise the words would be,

from the ruler of the synagogue ;
which could not be, since he was still with Christ: hence some versions, as the Vulgate and Arabic, render them, "to the ruler of the synagogue"; and which give a true sense, and a right view of the case; for this messenger both came from his house, and to him:

saying to him, your daughter is dead, trouble not the master ;
to bring him any further, since all hope of help was now gone. The Vulgate Latin version, instead of "master", reads "him"; and the Ethiopic version, "Jesus".
