'Supporter' in the Bible

Even now my witness is in heaven, and the supporter of my cause is on high.

For I was a saviour to the poor when he was crying for help, to the child with no father, and to him who had no supporter.

The Lord is my heritage and the wine of my cup; you are the supporter of my right.

See, God is my helper: the Lord is the great supporter of my soul.

And at that time Michael will take up his place, the great angel, who is the supporter of the children of your people: and there will be a time of trouble, such as there never was from the time there was a nation even till that same time: and at that time your people will be kept safe, everyone who is recorded in the book.
