brother Sambo talked about two angels "Goodness and Mercy" (see 59:20); even though he said he had never heard about them before, some time ago I heard Pastor Daniel Ekechukwu say the same thing in a video (which he gave around 2012) while testifying about how he was raised from the dead. in that testimony he also said he was told about two angels Goodness and Mercy. You can watch Pastor Daniel say this in the video "Raised from the dead - Daniel Ekechukwu in Rome (3)". He talks about the angels Goodness and Mercy in 16:30 and 17:10 of this video. this video is on youtube
