'Signs' in the Bible

This is what the Lord has said: Do not go in the way of the nations; have no fear of the signs of heaven, for the nations go in fear of them.

And you are not to give attention to your prophets or your readers of signs or your dreamers or those who see into the future or those who make use of secret arts, who say to you, You will not become servants of the king of Babylon:

For this is what the Lord of armies, the God of Israel, has said: Do not let yourselves be tricked by the prophets who are among you, and the readers of signs, and give no attention to their dreams which they may have;

Truly, after I had been turned, I had regret for my ways; and after I had got knowledge, I made signs of sorrow: I was put to shame, truly, I was covered with shame, because I had to undergo the shame of my early years.

Put up guiding pillars, make road signs for yourself: give attention to the highway, even the way in which you went: be turned again, O virgin of Israel, be turned to these your towns.

You have done signs and wonders in the land of Egypt, and even to this day, in Israel and among other men; and have made a name for yourself as at this day;

And have taken your people Israel out of the land of Egypt with signs and with wonders and with a strong hand and an outstretched arm, causing great fear;

But they had no fear and gave no signs of grief, not the king or any of his servants, after hearing all these words.

All you who are round about him, give signs of grief for him, and all you who have knowledge of his name, say, How is the strong rod broken, even the beautiful branch!
