The location on the banks of the river Rhine allowed Utrecht to become an important trade centre in the Northern Netherlands. The growing town Utrecht was granted city rights by Henry V in 1122. When the main flow of the Rhine moved south, the old bed, which still flowed through the heart of the town became evermore canalized; and the wharf system was built as an inner city harbour system. On the wharfs storage facilities (werfkelders) were built, on top of which the main street, including houses was constructed. The wharfs and the cellars are accessible from a platform at water level with stairs descending from the street level to form a unique structure.[nb 2] The relations between the bishop, who controlled many lands outside of the city, and the citizens of Utrecht was not always easy. The bishop, for example dammed the Kromme Rijn at Wijk bij Duurstede to protect his estates from flooding. This threatened shipping for the city and led the city of Utrecht to commission a canal to ensure access to the town for shipping trade: the Vaartse Rijn, connecting Utrecht to the Hollandse IJssel at IJsselstein.

Athanasius knew Greek and admitted not knowing Hebrew [see, e.g., the 39th Festal Letter of St. Athan.]. The Old Testament passages he quotes frequently come from the Septuagint Greek translation. Only rarely did he use other Greek versions (to Aquila once in the Ecthesis, to other versions once or twice on the Psalms), and his knowledge of the Old Testament was limited to the Septuagint. Nonetheless, during his later exile, with no access to a copy of the Scriptures, Athanasius could quote from memory every verse in the Old Testament with a supposed reference to the Trinity without missing any.[citation needed] The combination of Scriptural study and of Greek learning was characteristic of the famous Alexandrian School.
Did he understand Hebrew?
not knowing Hebrew

Israel has two official languages, Hebrew and Arabic. Hebrew is the primary language of the state and is spoken everyday by the majority of the population, and Arabic is spoken by the Arab minority and Hebrew is taught in Arab schools. English was an official language during the Mandate period; it lost this status after the creation of Israel, but retains a role comparable to that of an official language, as may be seen in road signs and official documents. Many Israelis communicate reasonably well in English, as many television programs are broadcast in English with subtitles and the language is taught from the early grades in elementary school. In addition, Israeli universities offer courses in the English language on various subjects. As a country of immigrants, many languages can be heard on the streets. Due to mass immigration from the former Soviet Union and Ethiopia (some 130,000 Ethiopian Jews live in Israel), Russian and Amharic are widely spoken. More than one million Russian-speaking immigrants arrived in Israel from the former Soviet Union states between 1990 and 2004. French is spoken by around 700,000 Israelis, mostly originating from France and North Africa (see Maghrebi Jews).
