'Busily' in the Bible

All these were busily engaged with one mind in prayer, together with the women and Mary the mother of Jesus and with his brothers.

For because of this you also pay taxes, for [the authorities] are servants of God, busily engaged in this very [thing].

Therefore, my dear brethren, be firm, unmovable, busily occupied at all times in the Lord's work, knowing that your toil is not fruitless in the Lord.
