2 Kings 4
Elisha multiplies the widow’s oil—He promises a son to a Shunammite woman—The child dies and is raised to life by Elisha—He makes the poisonous food harmless—Bread and grain are multiplied for the people to eat.
2 Kings 4:29
I read this as "don't let anything interfere with the commandment of the prophet." Not just go and do, but don't be distracted by something secondary, but also helpful (if the saluting is to mean social involvement, meeting with friends and family).
