'Midst' in the Bible

Before the throne was something like a sea of glass, similar to crystal. In the midst of the throne, and around the throne were four living creatures full of eyes before and behind.

I saw in the midst of the throne and of the four living creatures, and in the midst of the elders, a Lamb standing, as though it had been slain, having seven horns, and seven eyes, which are the seven Spirits of God, sent out into all the earth.

I heard a voice in the midst of the four living creatures saying, "A choenix of wheat for a denarius, and three choenix of barley for a denarius! Don't damage the oil and the wine!"

for the Lamb who is in the midst of the throne shepherds them, and leads them to springs of waters of life. And God will wipe away every tear from their eyes."
