Genesis 1: 27-28 Voice Version says: So, God did just that. He created humanity in His image, created them male and female. Then God blessed them and gave them this directive: “Be fruitful and multiply. Populate the earth. I make you trustees of My estate, so care for My creation and rule over the fish of the sea, the birds of the sky, and every creature that roams across the earth.”
It means to grow and multiply, especially at God’s pace. Fruitfulness means to prosper consistently and have dominion.
1Timothy 4:15 AMPC say: Practice and cultivate and meditate upon these duties; throw yourself wholly into them [as your ministry], so that your progress may be evident to everybody.
Psalm 2:7-8 MSG says: Let me tell you what God said next. He said, “You’re my son, and today is your birthday. What do you want? Name it: Nations as a present? continents as a prize?
