'Waver' in the Bible

And immediately Jesus, having stretched forth the hand, laid hold of him, and saith to him, 'Little faith! for what didst thou waver?'

and having seen him, they bowed to him, but some did waver.

"Therefore, do not be asking what you are to eat nor what you are to drink; and do not waver between hope and fear.

He did not waver in unbelief at God’s promise but was strengthened in his faith and gave glory to God,

let us hold fast the confession of our hope that it waver not; for he is faithful that promised:

And have mercy on those who waver;
