Boasted confidence but with humble heart in God

Ezra 8:1-36
Ezra's party of over 1700 includes priests, people and somewhat reluctantly, Levites.
Ezra assembled the family from Babylon at the canal that flows toward Ahava, he found no Levies there, so he summoned the leaders to bring capable man from the descendants of Mahlia son of Levi.
Ezra proclaimed a fast so that they might humble themselves before the God and ask him for a safe journey for them.
Ezra set apart twelve of the leading priests, together with sherebiah, Hashabiah and ten of their brothers, he weighed out to them the offering and the articles that the king, his advisers, his officials and all Israel present there had donated for the house of God. Ezra weighted out to them, and they weighted out to be taken to the house of God in Jerusalem. Everything was accounted for by number and weight, and the entire weight was recorded at that time.
With them they take as gifts 22 tonnes of silver and 3400kg of gold. Ezra is faced with a long and dangerous journey at a time of great unrest.And, having boasted his confidence in God, he can hardly now apply to the king for an escort! His prayer is heartfelt, and his faith rewarded by God's own safe-conduct.
Why?
Ezra knew what he is doing, so he assemble those peoples will go with him and checked the needed persons to serve the Lord. second he proclaim for fast and pray for the safe journey, then he carefully weighted the donated golds and silvers, and recorded the number.
Even Ezra has confidence the hand of God is over him but he asked king for soldiers and horsemen to protect them from enemies on the road.
The faith and altitude of Ezra to serve the Lord is our good example.
How?
Confidence with humble in our heart so that the confidence won't turn to proud which may cause some false or fell.
