There are several meanings, depending on which text you are referring to; however the Bible is very literal and the definition and use of this word is either self explanatory, or a description is included in the passage, such as Joel 2:2 "a day of darkness and gloom, a day of clouds and blackness. Like dawn spreading across the mountains a large and mighty army comes..." referencing the same meaning as Ezekiel 38:9 "You and all your troops... Advancing like a storm, you will be like a cloud covering the land..."
For instance, in Genesis 9, "clouds" refers to clouds in the sky, as we see them.
In Exodus 13 & 14, The Lord and his angel(s) appeared in clouds similar to a pillar of smoke
In Exodus 40, it was a dense fog
In Lamentations 2 & 3, the clouds are like foreboding, cloaking shadows
Hebrews 12:1 refers to a large gathering of people, once again self explanatory: "surrounded by such a great cloud of witnesses"
Jude 12 describes men, in the following text: "These men are blemishes... Clouds without rain blown along by the wind"
Revelations 1:7 "He is coming with the clouds" is literal, fulfilling Daniel 7:13 and Matthew 24:30 :clouds of the sky, or clouds of Heaven.
In Matthew 24:30; 26:64; Mark 13:26; 14:62; Luke 21:27; I Thessalonians 4:17; when the reference is made as either "in the clouds" or "on the clouds", that's what it means: There is no reason or cause to speculate that "well, he really meant <this> or <that> or <like a cloud>". These passages don't even lend themselves for the need for other interpretation - we know that He is coming in the sky, and we will go to meet Him in the sky, so why speculate that <clouds doesn't mean "cloud" clouds, but a group of people>? Christ is coming, and those of us who know Him are going. THAT is all that matters!
