What does Jeremiah 46:28 mean?

Fear not thou, O Jacob my servant, saith Jehovah; for I am with thee: for I will make a full end of all the nations whither I have driven thee; but I will not make a full end of thee, but I will correct thee in measure, and will in no wise leave thee unpunished.

Fear thou not, O Jacob my servant, saith the Lord: for I am with thee; for I will make a full end of all the nations whither I have driven thee: but I will not make a full end of thee, but correct thee in measure; yet will I not leave thee wholly unpunished.

Fear not thou, O Jacob my servant, saith Jehovah; for I am with thee: for I will make a full end of all the nations whither I have driven thee; but I will not make a full end of thee, but I will correct thee in measure, and will in no wise leave thee unpunished.

Have no fear, O Jacob, my servant, says the Lord; for I am with you: for I will put an end to all the nations where I have sent you, but I will not put an end to you completely: though with wise purpose I will put right your errors, and will not let you go quite without punishment.

Thou, thou dost not fear, My servant Jacob, An affirmation of Jehovah--for with thee I <FI>am<Fi> , For I make an end of all the nations Whither I have driven thee, And of thee I do not make an end, And I have reproved thee in judgment, And do not entirely acquit thee!'

And thou, my servant Jacob, fear not, saith the Lord: because I am with thee, for I will consume all the nations to which I have cast thee out: but thee I will not consume, but I will correct thee in judgment, neither will I spare thee as if thou wert innocent.

Fear thou not, my servant Jacob, saith Jehovah: for I am with thee; for I will make a full end of all the nations whither I have driven thee, but I will not make a full end of thee; but I will correct thee with judgment, and I will not hold thee altogether guiltless.
