'One by one' in the Bible

Behold, this have I found, saith the preacher, counting one by one, to find out the account:

And it shall come to pass in that day, that the LORD shall gather from the channel of the river to the stream of Egypt, and ye shall be gathered one by one, O ye children of Israel.

And they began to be sorrowful, and to say to him one by one, Is it I? and another said, Is it I?

And they who heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even to the last: and Jesus was left alone, and the woman standing in the midst.

For ye may all prophesy one by one, that all may learn, and all may be comforted.
