Yes, you'll recall the Spirit is right there in the beginning. I mean "In the beginning ...." like Genesis 1. The Spirit didn't appear unknown to God's people at Pentecost.
In Numbers 11, a despairing Moses begs for God's intervention with these impossible people for whom God has made him the responsible leader. They are never content and always complaining. Moses can't take it any longer.
God has an answer, but Moses doubts its efficacy. God's reply is a keeper: "Is the Lord's arm too short?"
Gathering 70 elders in the tabernacle, Moses is somehow able to share out the Spirit in/with him with those gathered, and even with two who didn't get the memo and missed the meeting. The Spirit took care of business, empowering the elders to begin taking on some of the leadership role.
The role of the Spirit is something Paul teaches to the Galatians. After a burning hot start to his letter, by chapter 5 he has settled down and teaches wonderfully about the effect of the Spirit's leadership and how it should be manifested by faithful disciples.
