Charles Ellicott Commentary 1 Chronicles 19:1

"And it came to pass after this, that Nahash the king of the children of Ammon died, and his son reigned in his stead." — 1 Chronicles 19:1 (ASV)

Now it came to pass after this. —The same phrase as in 1 Chronicles 18:1; it has no chronological significance (see Note there). The conflict with Ammon, which has been glanced at in 1 Chronicles 18:11, is now to be described at length (1 Chronicles 19:1 to 1 Chronicles 20:3), and in connection with this, the overthrow of Hadadezer (1 Chronicles 18:3–8) is again related, with additional details.
