Job 26:7 two words are in play, hang and nothing.
In strongs hang is, 8518. talah and also in strongs nothing is 1099. belimah.
belimah is not used any where else in the Bible so it is this word that is hard to test the meaning of from the Bible.
But talah is use and in its use it is always to hang, suspend, or support by actual contact.
The Hebrew word talah means to hang, suspend, or support by actual contact, not by nothing
Examples:
Genesis 40:19,
Psalms 137:2,
Ezekiel 15:3
From Terra Firma: By David Wardlaw Scott
belimeh wrongly translated "nothing" is the crucial word. translators appear to have derived it from the noun blee, signifying consumption or desolation, and the pronoun meh, who which what, but the meaning "nothing" drawn from these words, seems to be very far fetched. Hebrew is a very ancient language, to all probability the most ancient of any, and this being the only place in the Bible where the word belimeh occurs, it is, of course, difficult to test the meaning. I have myself, however, not the slightest doubt, that Parkhurst is right in deriving the noun belimeh from the verb belem, to confine, restrain, or hold in, so used in
Psalm 32:9 Do not be like the horse
or like the mule,
Which have no understanding, Which must be harnessed(belem) with bit and bridle, Else they will not come near you.
and that belimeh simply means "fastenings," or "supports," and this interpretation exactly agrees with what God asked Job a little farther on in
Job 38:6 To what were its foundations fastened?
Or who laid its cornerstone, But while I consider Parkhurst to be correct as to the rendering of the word belimeh, I believe him to be wrong as to the strange application of it which he makes.
-------------
The Bible several times states the earth is set on foundations. Never is it stated in the Bible except in the wrongly translated
Job 26:7 the earth hangs on nothing. That idea has been imported into the Bible from translators who want the Bible to in this one verse agree with science.
