'Seven' in the Bible

These six were born to David in Hebron; he reigned there seven years and six months, and in Jerusalem he reigned thirty-three years.

The sons of Elioenai: Hodaviah, Eliashib, Pelaiah, Akkub, Johanan, Delaiah, and Anani—seven in all.

Their relatives from the households of their fathers: Michael, Meshullam, Sheba, Jorai, Jacan, Zia, and Eber—seven in all.

Their relatives in their villages were to come in every seven days from time to time to be with them;

all the brave men arose, took away the body of Saul and the bodies of his sons and brought them to Jabesh, and they buried their bones under the oak in Jabesh; then they fasted seven days.

They helped David against the band of raiders, for they were all courageous men, and [all seven] became commanders in his army.

Because God was helping the Levites who carried the ark of the covenant of the Lord [to do it carefully and safely], they sacrificed seven bulls and seven rams.

The time that he reigned over Israel was forty years; he reigned seven years in Hebron and thirty-three years in Jerusalem.
