I would reply, “No, it certainly does not mean that! God always does what he has promised, even though people do not. All those who accuse God of not keeping his promises to us Jews are very mistaken.” What King David wrote about God’s justly saying that he would punish him for his sins is also true of those who accuse God of not keeping his promises. What he said to God was, “So everyone must acknowledge that what you (sg) have said about them (OR, their sin) is true, and you will always win the case when you are accused {when people accuse you}.”
