Ibn Ezra

מנדיכם That cast you out. Comp. ינדוהו they chase him (Job 18:18). Some render it those in whose eyes you are considered as doomed. Your brethren is added, because this circumstance, that they are brethren, gives greater force to the offence. יכבד יי R. Moses Hakkohen says, that it means, the Lord is heavy; that is, it is difficult to them to remember Him and to keep His commandments; as a proof of the correctness of this explanation he adds, that only the Niphal of כבד is found in the meaning of to be honoured, as e.g. נכבדת Thou art glorified (26:15); but he did not think of יִבְבְּדוּ they are honoured, which is the opposite of יצערו they are little (Job 14:21). According to this explanation the sense of the verse is clear. After יכבד יי the Lord is heavy the word yet must be supplied once, yet, or are the corruption of ותחסר מלת עוד, as adopted for the translation., as if the prophet said, yet a time will come, when we shall see your rejoicing, while they, that cast you out, will be confounded. But I think that these are the words of your brethren that cast you out, and that the whole verse must be explained thus: Your brethren say, For my name’s sake let the Lord be honoured [יכבד being derived from כבוד honour (11:10)], we wish it that the Lord be honoured, then we shall see your rejoicing and be ashamed; this is the meaning of the words והם יבשו and they shall be ashamed. They say it ironically and mean to indicate, that God will not be able to show His glory. In this way there is a connection between this verse and the next. Those that take these words, not as uttered by your brethren etc., but spoken by God, understand the plural in נראה as pluralis majestatis, like the plural in נעשה let us make (Gen. 1:26), or refer it to both, to God and the prophet together.
