For you should know that … : The connector For may be omitted, so translators may begin this verse with “You should know…” or “I want you to know that….”

If we devise any evil against them may be rendered “if we are planning to do any evil against the Jews.”

Or cause them any grief at all may be translated “or cause them any trouble [or, harm] at all” (Contemporary English Version).

We always shall have not man but the Ruler over every power, the Most High God, in everything and inescapably as an antagonist to avenge such acts: The king tells his military officers and government officials that if anyone attempts to harm the Jews, they will have to deal with God, not just with human beings. Here the pronoun we seems to include the king and the other Egyptian leaders. An antagonist is an opponent. God will be the opponent of anyone who tries to harm the Jews. A possible model for this part of the verse is “We will not have a human ruler opposing us; but God Most High himself, who rules over all earthly rulers, will oppose us. He will certainly punish anyone who hurts the Jews.”

Farewell marks the end of the king’s letter. It may be translated by any customary way of closing a letter, especially a formal letter.

Here is an alternative model for this verse:

• You may be sure that if we plan to do anything evil against the Jews, or harm them in any way, we will not have a human ruler opposing us; but the Most High God, who rules over all earthly rulers, will oppose us. He will certainly punish anyone who does such things to the Jews. Good-by.”
