What caused Avimelech and Pichol to proclaim that HaSh-m was with Avraham in all his endeavors?
1.
Rashi: The fact that a) he emerged from the area of Sedom unscathed, b) the four kings fell into his hands and c) his wife bore him a son in his old age. 1
2.
Seforno and Rashbam: They came to make a covenant with him due to the miracles that Avraham had experienced, out of the awe they felt towards him; not because they were afraid of Avraham's strength and his wealth.

Gur Aryeh: If so, why did they reach this conclusion only now? This was the third salvation that HaSh-m had granted Avraham, which created a Chazakah.
