Revelation 13 cannot be properly understood without Daniel 7

In Revelation 13 it is talked about a beast coming from the sea (verse 1), a beast coming from the earth ( verse 11) and and a living image (or idol) of the beast (verse 14) that has to be worshipped as a god (verse 15) but in fact is a human (verse 18).

Beast from the sea
In Daniel 7 four beasts come from the sea:

Daniel 7:3 And four great beasts were coming up from the sea, different from one another.

They look like a lion, bear and leopard, but the fourth is unspecified (verses 4-7).

In verse 23 it says those beasts are KINGDOMS:

Daniel 7:23 “This is what he said: ‘The fourth beast will be a fourth kingdom on the earth which will be different from all the other kingdoms, and will devour the whole earth and trample it down and crush it.

Those kingdoms can be identified as the Babylonian empire, the Persian empire, the Greek empire of Alexander the Great which was divided among his four generals and the Roman Empire.

The beast from the sea in Revelation 14 consists of a lion, bear and leopard:

Revelation 13:2 And the beast that I saw was like a leopard, and his feet were like those of a bear, and his mouth like the mouth of a lion.

It means this can be the fourth beast of Daniel 7, being the Roman empire.

Beast from the earth
Verse 17 of Daniel 7 says that those four beasts are also four kings rising from the earth:

Daniel 7: 17 ‘These great beasts, which are four in number, are four kings who will arise from the earth.

Yet the four empires had way more than just one king each. Therefore this could be understood as KINGSHIPS. The four empires had four typical kingships with multiple successive kings ruling the empires. Thus a beast coming from the earth can be seen as the kingship of that empire.

Image of the beast

If the above makes sense then the 'image of the beast' that can breath and speak can be understood as the specific emperor of the Rome at that given moment, like Nero for instance. He is the living statue of a god or idol, his image is on coins without which nobody can sell or buy. He looks like the lamb, pretending to be God and wanted to be worshipped as God, but he is just human.

Like this, we can see that Daniel 7 and Revelation 13 are two sides of one coin. They are two halfs of one story. Revelation 13 takes off where Daniel 7 stopped. It finished and completes Daniel 7. And thus Revelation 13 cannot be properly understood without Daniel 7.
