 Other fragments of this text have been found in Caves 1 and 4 (1Q35, 4Q427–432).But even when these readings are added to 1QHa, there is still a substantial amount of text missing.Scholars can only speculate how many hymns/poems/psalms were included in this work, but it is fairly certain that more than half of the psalms have survived, though not always in complete form.
