The language here would seem to be taken from Daniel 7:10; "Thousand thousands ministered unto him, and ten thousand times ten thousand stood before him."
Ngokufanayo, kuDaniel 7: 10 sithola ukuthi: "Inkulungwane zamkhonza, futhi izinkulungwane eziyishumi eziphindwe kayizinkulungwane eziyishumi zema phambi kwakhe."
