ἐκβάλλω ekballo [verb] : to violently thrust forth
In Matthew 9:38, there is a command from Jesus regarding the great need of millions who had never heard of the gospel. When He said that "The harvest is plentiful, but the laborers are few," He commanded His disciples: "Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest." The word for send He uses here is not the typical word for send, but rather the greek word, "ekballo." This is the same word that Jesus uses when He casts out demons by the finger of God (Luke 11:20), and when Jesus Himself is ekballoed into the wilderness by the Holy Spirit (Mark 1:12).
This is not just a great suggestion, but a passionate casting forth by the Spirit of God so that laborers are compelled to go!
It has been said that there is no great movement of God that has ever occurred that does not begin with the extraordinary unified prayer of God’s people. The fulfillment of the great commission is no exception! The Lord is desirous of a people who will partner with Him in praying forth laborers into His harvest field, and also become the answers to their own prayers.
