Why does the Old Testament teach that the Holy Spirit came upon people?

The Bible teaches that during Old Testament times the Holy Spirit came upon people to give them power to do jobs they couldn’t do on their own.

The Bible teaches that God gave some people jobs that were too difficult for them to do on their own. God knew that they couldn’t do the jobs alone so he sent his Holy Spirit to be with them. When the Holy Spirit came upon them he gave them power to do the jobs they needed to do; he gave them the power to do something that they couldn’t do on their own.The Bible tells us that they were empowered by the Holy Spirit.

In the Old Testament we read that the Holy Spirit came upon Bezalel (Exodus 31:1–5), Moses (Numbers 11:25), Samson (Judges 15:13–14) and King Saul (1 Samuel 10:9–11). The Holy Spirit empowered them to do different ‘jobs’.

In the book of Zechariah, God’s message to Zerubbabel was that he would finish the Temple not by his own might nor by his own power but by God’s Spirit. God was promising Zerubbabel that his Holy Spirit would help him to finish the Temple. The Holy Spirit would empower Zerubbabel. Using his own power or even working with other people Zerubbabel wouldn’t be able to finish the Temple, he needed God’s help; he needed the power of the Holy Spirit.

Today Christians believe that, on the day of Pentecost, the Holy Spirit came to be with Christians in a new way - he no longer just empowers a few people; he comes and lives in Christians, he works powerfully in their lives and he is with them all the time.
