tn The disjunctive clause (note the pattern conjunction + subject + implied “to be” verb) is parenthetical, telling the age of Abram when he left Haran.

tnHeb “was the son of five years and seventy year[s].”
sn Terah was 70 years old when he became the father of Abram, Nahor, and Haran (Gen 11:26). Terah was 205 when he died in Haran (11:32). Abram left Haran at the age of 75 after his father died. Abram was born when Terah was 130. Abram was not the firstborn—he is placed first in the list of three because of his importance. The same is true of the list in Gen 10:1 (Shem, Ham and Japheth). Ham was the youngest son (9:24). Japheth was the older brother of Shem (10:21), so the birth order of Noah’s sons was Japheth, Shem, and Ham.
