The Bible uses the term "Malachim" (Hebrew for "messengers"), which is
often translated as "angels"; see, for example, Genesis 16:7 and 19:1.
The Jewish tradition is that the angels were created on the second day, and that G-d consulted them when He decided to create man on the sixth day (see Genesis 1:26). They serve as G-d's messengers to this world; see Genesis 28:8, where Jacob dreams of angels coming down to earth and returning to heaven.
