Adam Clarke on Daniel 2:4

Then spake the Chaldeans to the king in Syriac - ארמית aramith, the language of Aram or Syria. What has been generally called the Chaldee.

O king, live for ever - מלכא לעלמין חיי Malca leolmin cheyi. With these words the Chaldee part of Daniel commences; and continues to the end of the seventh chapter. These kinds of compliments are still in use in the East Indies. A superior gives a blessing to an inferior by saying to him, when the latter is in the act of doing him reverence, "Long life to thee." A poor man, going into the presence of a king to solicit a favor, uses the same kind of address: O father, thou art the support of the destitute; mayest thou live to old age! - Ward's Customs.
