Daniel 12:3

They that be wise. Heb. hammaskilim, from the verb sakal, “to be prudent.” The form may be understood either in a simple sense, as “those who are prudent,” “those who have insight,” or in a causative sense, “those who cause to have insight,” that is, “those who teach.” The man who truly has insight into the things of God realizes that, by virtue of that very fact, these things must be shared with others. Divine wisdom leads him to be a teacher of that wisdom to others.

Maskilim appears in Daniel 11:33, where it is translated, “they that understand.” There they are shown as persecuted for their faithful endeavors; here they are rewarded with eternal glory. Compare verse 10.
