ט וַתֹּאמֶר לוֹ אִשְׁתּוֹ, עֹדְךָ מַחֲזִיק בְּתֻמָּתֶךָ; בָּרֵךְ אֱלֹהִים, וָמֻת.
"And his wife told him, you still cling to your innocence; bless God, and die. "
the word ברך Barech, means bless (in the commanding form of the verb).
What the verse actually means, is that the wife advices Job to curse God so that he would die and his miseries end.
