"Constrained to speak"

1. 1 Ne. 7: 15
   15 Now behold, I say unto you that if ye will return unto Jerusalem ye shall also perish with them. And now, if ye have choice, go up to the land, and remember the words which I speak unto you, that if ye go ye will also perish; for thus the Spirit of the Lord constraineth me that I should speak.
2. 2 Ne. 4: 14
   14 For I, Nephi, was constrained to speak unto them, according to his word; for I had spoken many things unto them, and also my father, before his death; many of which sayings are written upon mine other plates; for a more history part are written upon mine other plates.
3. Hel. 8: 11
   11 Therefore he was constrained to speak more unto them saying: Behold, my brethren, have ye not read that God gave power unto one man, even Moses, to smite upon the waters of the Red Sea, and they parted hither and thither, insomuch that the Israelites, who were our fathers, came through upon dry ground, and the waters closed upon the armies of the Egyptians and swallowed them up?
