Certainly not all the bows of the Middle East were composite bows. Archeologically datable Old Testament sites date back to the Neolithic period, if I remember correctly, and composite bow technology is much more recent than that. The composite bow was by all accounts introduced to Egypt by the Hyksos, in the period known as the Second Intermediate (1700-1775 BC).
I did some data-mining, and discovered a British Museum Technical Report on Egyptian self-bows in their collection. All of the specimens have been dated to pre-Christianity, and as far back as pre-dynastic Egypt (the New Stone Age). You can download your own PDF of the report at this address:

Ziziphus spina-christi) is a tropical evergreen tree (but not a pine) common to North Africa and the Middle East. It grows in Israel in the valleys and low elevations below 1500 ft.
AbstractThe woods of 15 Egyptian wooden archery bows from the collections of the British Museum,
ranging in date from the Neolithic period to the New Kingdom have been scientifically identified. The objects
studied included bows from Asyut and from the tomb of Mentuhotep II at Deir el-Bahri. Microscopical
examination of millimetre-sized samples revealed that all the bows were made from indigenous Egyptian
woods. Acacia (
Acacia sp.) and Sidder (
Ziziphus spina-christi) woods were preferentially selected, with seven
bows of acacia and six of Sidder. These woods have a high proportion of the properties needed for optimum
functioning as archery bows, i.e. resilience, flexibility, elasticity and strength. Tamarisk wood (
Tamarix sp.),
a less suitable choice of timber for bows, was used for the remaining two artefacts.
Across Europe, the Mediterranean region and the Middle East, three main forms of bow have been recog-
nized. The earliest form, the self bow, was made from a single piece of wood, often a long stave to allow addi-
tional draw length. The use of a single piece of wood reduced the risk of mechanical weakness or fracturing.
The other two forms of bow were backed bows (made from two layers of wood glued together) and composite
bows, the most sophisticated form, in which the wood was bonded to other materials such as antler, horn
and sinew. With the exception of one, whose attribution as a bow is uncertain, the artefacts in this study are
self bows.
