Book of Jubilees 47:4
And thy mother hid thee for three months, and they told regarding her. And she made an ark for thee, and covered it with pitch and asphalt, and placed it in the flags on the bank of the river, and she placed thee in it seven days, and thy mother came by night and suckled thee, and by day Miriam, thy sister, guarded thee from the birds.
Background and history of Book of Jubilees, and issues with this book.
R. H. Charles, The Book of Jubilees, in The Apocrypha and Pseudepigrapha of the Old Testament, vol. 2 (Oxford: Clarendon Press, 1913). Public domain in the United States (published 1913). Charles died in 1931, so the book is in the public domain in the United Kingdom. The verse text is the Joshua Williams transcription at pseudepigrapha.com. Jubilees 1:8 and 1:9 are divided at the break in the 1902 Clarendon scan (archive.org bookofjubileesor00char), where verse 9 begins “For they will forget.” That scan also numbers the angel-of-the-presence sentence as 1:29. Editorial brackets in the translation are Charles’s.
