they spread

"they set up"

Absalom went to his father's concubines

This is a polite way of saying that he had sexual relations with them. See how you translated a similar phrase in 2 Samuel 16:21.(See: rc://en/ta/man/jit/figs-euphemism)

in the sight of all Israel

This means that people were able to see the tent and Absalom walking in and out of the tent with the women. The phrase "all of Israel" is a generalization, for only people near the palace could see it. Alternate translation: "where the Israelites could see him go into the tent" (See: rc://en/ta/man/jit/figs-hyperbole)
