Matthew Poole and continuators on Joshua 9:16

16 ¶ And it came to pass at the end of three days , after they had made a league with them, that they heard that they were their neighbours, and that they dwelt among them.

i. e. At the last of them, or upon the third day, as it is said, v. 17. and so this Phrase is elsewhere used, as Deut. 14. 28. and 31. 10. Or it may be properly understood, that after three days they heard this, and on the day after they heard this, they came to their Cities, as is said, v. 17.
