110:3 Your people shall be volunteers In the day of Your power; In the beauties of holiness, from the womb of the morning, You have the dew of Your youth. (NKJV)

110:3 Your people will offer themselves willingly on the day you lead your forces on the holy mountains. From the womb of the morning, like dew, your youth will come to you. (NRSV)

110:3 Thy people offer themselves willingly, In the day of thy power, in holy array: Out of the womb of the morning Thou hast the dew of thy youth. (AMS)

110:3 When you go to war, your people will serve you willingly. You are arrayed in holy garments, and your strength will be renewed each day like the morning dew. (NLT)

I needed to list all these translations so were clear on what God was saying through King David. In order to be part of God's kingdom, you have to volunteer for it through Jesus Christ. It's a calling that God extends to everyone. Once you hear that calling and are willing to listen to God, then you're on your way to an eternal kingdom. You're preparing for the battle that God's people have to encounter everyday.
