וַיַּ֤עַשׂ לָהֶם֙ מִשְׁתֶּ֔ה וַיֹּאכְל֖וּ וַיִּשְׁתּֽוּ׃
И он сделал им пиршество, и они ели и пили.
Radak on Genesis
ויעש להם משתה, in order to preserve the friendly atmosphere he prepared a feast for them and they ate and drank together.
Haamek Davar on Genesis
He made a feast for them. It is the way of the righteous to be easily appeased.
