Jehovah
Go and speak to Ebedmelech the Ethiopian, saying, Thus saith the LORD of hosts, the God of Israel; Behold, I will bring my words upon this city for evil, and not for good; and they shall be accomplished in that day before thee. Jeremiah 39:16–18
Jehovah, the premortal Christ, promises to save Ebedmelech, a foreigner who rescued His prophet, because he trusted in Him. The Lord delivers all who put their trust in Him, whatever nation they come from.
