Sgt. Gilad Yacoby, 21, from Kiryat Ono was laid to rest in Kiryat Shaul Cemetery in Tel Aviv Monday morning.
Yacoby was killed in action on July 20 along with 12 other soldiers from the Golani brigade in what was the deadliest day yet of Israel's Operation Protective Edge.
Yacoby's military rank will be posthumously upgraded to Staff Sergeant, the IDF said.
The names of six of the other soldiers killed Sunday were also released.
Maj. Tzafrir Bar-Or, 32, from Holon; Capt. Tzvika Kaplan, 28, from Kdomim; Sgt. Oz Mandelovich, from Avtalion; and Sgt. Sean Carmeli, 21, from Ra'anana, Staff Sgt. Moshe Malko of Jerusalem, and Max Steinberg, from Beersheba.
The military was still completing the process of identifying the remaining fallen soldiers. The families had been notified of the soldiers' deaths.
In one incident, in the early hours of Sunday morning, an APC carrying soldiers from Golani's 13th Battalion drove over an explosive device and caught fire, killing seven who were onboard.
Shortly afterward, soldiers from the battalion engaged terrorists in a gun battle, and one soldier was killed in the exchange of fire.
Hours later, two soldiers were killed in a firefight with a terrorist cell in Gaza.
Three members of the Golani Reconnaissance Brigade were killed when a fire tore through the building they were in, shortly before 9 a.m.
