What does Ezra 8:22 mean?

I was embarrassed to ask the king for soldiers and horsemen to protect us from enemies on the road, because we’d told him, 'Our God takes care of everyone who trusts him, but his power is against anyone who abandons him.' Ezra 8:22 - Modern Text Bible

(Ezra feels responsible to live out the faith he’d spoken about to the king, so he relies on God instead of asking for military help.)
