Behold, he reached out

"He did something even worse than that: he reached out"

reached out with his hand to make a promise

This refers to taking hold of another person's hand as a sign of friendship and agreement. Here it represents the covenant oath that he made with the king of Babylon. (See: rc://en/ta/man/jit/translate-symaction)
