The paleo Phoenician-Canaanite-Byblian, Old Aramaean, and Moabite alphabetic scripts have a unique letter ‘aleph, in the shape of an ox head, where the vertical stroke crosses two diagonal strokes at or very close to their apex. However, on the inscribed artifacts of genuine "Israelite" manufacture, whether pre-exilic or post-exilic, the first letter of the paleo alphabetic script is a vertical stroke crossing two horizontals not two diagonals. The upper horizontal stroke is always wider than the lower horizontal stroke. Sometimes the strokes do form an apex, but given the length of the vertical stroke the head of an ox clearly is not being represented by this sign even when this happens. The "Israelite" letter always resembles a signpost or the shape of the Latin letter F. Since the Ghabaray/Hebrew word for "letter" is אות (oth) means "sign" it makes better interpretive sense that the first letter of the 22-letter alphabetic "Israelite" script represents an actual signpost (signs or flags attached to the upper part of a pole) and not the head of an ox.
In any event, there is no evidence that Ya'ohsharal obtained its alphabetic script from the Phoenician-Canaanites. Nor any empirical evidence whatsoever that the reverse wasn't in fact true and that the Phoenician-Canaanites adopted and modified the script of the 15th century "Habiru" conquerors of the Levant who recently escaped from Egyptian servitude in 1497 BC.
