‘ And Gideon went in and made ready a kid, and unleavened cakes of an ephah of flour. The flesh he put in a basket, and he put the broth in a pot, and brought it out to him under the oak and presented it.'
The broth suggests that the kid was boiled. The whole meal was of ultra-generous proportions as befitted such a guest. In view of their poverty-stricken situation this demonstrated how impressed Gideon was with his visitor. A whole lamb and an ephah of flour. The mention of an ephah of flour may suggest a sacrificial intent in Gideon's mind (compare Ezekiel 45:24). An ephah was far more than would be expected for a visitor, as was a whole kid (a tenth of an ephah would feed a man for a day). Gideon was still clearly in two minds about Him and was not sure whether to bring a meal or a sacrifice.
For the whole consider Genesis 18:6-8, where Yahweh was brought a feast b y Abraham, a passage which Gideon may have had in mind. But this was a feast indeed.
