Kehillah in Corinth I 10:10-12

Orthodox Jewish Bible

¹⁰ Neither should we murmur and grumble even as some of them VAYILONU ("and they murmured’ SHEMOT 15:24; 16:2; 17:3; BAMIDBAR 14:2,29; 16:41) and they were destroyed by the destroyer (Num 14:2,36; 16:41-49; 17:5,10; Ex 12:23 Ps 106:25-27).

¹¹ Now, these things happened to those ones as moftim (examples), but it was written for our admonition, to whom the Kitzei HaOlamim has come.

¹² So then the one that presupposes that he stands, let him take care lest he fall.
