I'm certainly no Hebrew expert. But the term in question is defined below by Strongs and is only seen in the verse list below.
H5957 `alam aw-lam'
(Aramaic) corresponding to H5769;
remote time, i.e. the future or past indefinitely; often adverb, forever.
KJV: for ((n-))ever (lasting), old.
Having thrown out some wildcards (such as when in Ezra 4:9 the root word for forever shows up as an element of "Elamites") and some repetition, the following are the uses of the Hebrew root that becomes forever in a number of passages including Daniel 7:18. The root is seen in "forever", "everlasting", and "old time":
