Who is the Lord of the Harvest?

Reflecting on Matthew 9:38, Matthew 10:1-42, and Luke 10:2, who is the Lord of the Harvest, God the Father or God the Son? Or both together along with the Holy Spirit due to the nature of the Trinity? Jesus in Matthew 9 says to pray to the Lord of the Harvest to send workers out into the harvest. In the Lord’s Prayer, Jesus had instructed his believers to pray to the Father. Then in Matthew 10, Jesus sends his disciples out into the harvest. This would seem to indicate that Jesus is the Lord of the Harvest, as he is answering this prayer and doing the sending. Was Jesus in an indirect way in Matthew 9 asking his disciples to pray to him? Or is the Father the Lord of the Harvest, who made the decision to send out laborers, told Jesus, and Jesus is merely revealing the Father’s decision? Please cite Reformed sources.
