Psalm 145:15-16: "15 The eyes of all look to you, and you give them their food in due season. 16 You open your hand; you satisfy the desire of every living thing."
Luke 24:29-30: "29 but they urged him strongly, saying, 'Stay with us, for it is toward evening and the day is now far spent.' So he went in to stay with them. 30 When he was at table with them, he took the bread and blessed and broke it and gave it to them."
James 1:17a: "Every good gift and every perfect gift is from above"

The hymn text is fairly general, but the passage from Luke 24 seems to be the main source (especially for "be our guest"), and the other cited texts are combined with it in "let these gifts to us be blest."
