'Diligently' in the Bible

This man had been instructed in the way of the Lord, and being spiritually impassioned, he was speaking and teaching accurately the things about Jesus, though he knew only the baptism of John;

In everything I showed you [by example] that by working hard in this way you must help the weak and remember the words of the Lord Jesus, that He Himself said, ‘It is more blessed [and brings greater joy] to give than to receive.’”
