As a Jew (tribe of Judah) and thus a Hebrew, He came in his Father's name. Certainly he told his disciples and others His name and His Father's name, as in Yahusha, coming in His Father's name Yahuah.
Most Bible prefaces and scholars say it is Yahweh, with the Son's name Yahushua (as in very similar to the Yehoshua, or in English Joshua).
So JWorg's The Truth is off track from simply transliterating Hebrew names (let alone the sounds of J and V not used by Hebrews, nor the J by Greeks or English intil the mid 1600s).
