"I told the principal and teachers that God had laid upon them the responsibility of watching for souls as they that must give account. I showed them that the wrong course pursued by some of the students would mislead other students, if it were continued, and for this God would hold the teachers responsible. Some students would attend school who had not been disciplined at home, and whose ideas of proper education and its value were perverted. If these were allowed to carry things in their way, the object for which the school was established would be defeated, and the sin would be charged against the guardians of the schools, as if they had committed it themselves.

"Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you."
The EGW passage explicitly references the responsibility of teachers 'watching for souls as they that must give account,' which is a direct allusion to Hebrews 13:17.
"God holds everyone responsible for the influence that surrounds his soul, on his own account and on the account of others. He calls upon young men and women to be strictly temperate, and conscientious in the use of their faculties of mind and body. Their capabilities can be properly developed only by the most diligent use of their opportunities and the wise appropriation of their powers to the glory of God and the benefit of their fellow men. CT 102.2"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage directly echoes the sentiment of glorifying God in one's body and spirit, emphasizing the responsibility for one's physical and mental faculties. The connection is strong and meaningful.
