However, it remains uncertain whether Moses performed any formal ordination, whether any external actions like blowing occurred, or if other miraculous signs, such as fire on the day of Pentecost when the Holy Spirit descended upon Christ's disciples, manifested during this occurrence.
When the Spirit descended upon them, the seventy elders began to prophesy, entering a state of divine ecstasy where they spoke forth what the Holy Spirit inspired. While the details are not specified, prophecy in biblical terms encompasses not only foretelling future events but also declaring God’s revelations that reflect His glory and serve as guidance and correction for humanity. It is believed that the prophetic words of the seventy were aimed at urging the children of Israel to cease their complaints against the Lord regarding their insufficient provisions and to return to a state of unwavering obedience to God’s will. They declared the miraculous acts God performed during the Exodus from Egypt, which were still evident in their midst. It is noteworthy that Christ's disciples, after receiving the Holy Spirit, similarly proclaimed God's mighty works.
In general, it can be inferred that the prophetic proclamations of the seventy elders were tied to their appointed ministry, illustrating the nature of their calling. However, this profound state did not persist; they did not continue in that rapturous utterance. Though their subsequent prophetic speech remained under the guidance of the Holy Spirit and strengthened by divine grace, the extraordinary signs that accompanied their initial experience, such as structured singing and lively movements, were not repeated. This initial manifestation of the Holy Spirit's work in the seventy was unique and enacted to provide visible confirmation of their anointing, as well as to signal their selection by God for leadership—a role that commanded the same obedience as Moses, their chosen leader.
There is a consensus that the ministry of the seventy elders, serving alongside Moses, continued throughout the Israelites' journey in the wilderness. However, the future trajectory of this council remains ambiguous, unless it is posited that it eventually evolved into the Sanhedrin, a governing body of seventy members that emerged after the Babylonian exile.
