Is the word Yahweh present in Rig Veda?

Question

This post from Swarajya claims the word Yahweh appears in Rig Veda multiple times.

The common thread is one word – Yahweh, which can be found in both the Rig Veda, and in the Old Testament – the oldest Abrahamic text.

Is the word Yahweh present in Rig Veda?
If yes then where exactly does the word Yahweh occurs in Rig Veda?

Answer 1

If by 'Yahweh' you mean the word यह्वं = yahvaṃ. Then yes, it does occur in the Rig-Veda.

Searching it on the sa.wiki repository yields multiple results of its occurrence (around more than 30)
in the Rig-Veda itself, besides other Vedas.

Some instances are -

ṛgvedaḥ sūktaṃ 1.36

प्र वो यह्वं पुरूणां विशां देवयतीनाम् । अग्निं सूक्तेभिर्वचोभिरीमहे यं सीमिदन्य ईळते ॥१॥

ṛgvedaḥ sūktaṃ 5.16

अधा ह्यग्न एषां सुवीर्यस्य मंहना । तमिद् यह्वं न रोदसी परि श्रवो बभूवतुः ॥४॥

ṛgvedaḥ sūktaṃ 8.13

तदिद्रुद्रस्य चेतति यह्वं प्रत्नेषु धामसु । मनो यत्रा वि तद्दधुर्विचेतसः ॥२०॥

ṛgvedaḥ sūktaṃ 10.92

इममञ्जस्पामुभये अकृण्वत धर्माणमग्निं विदथस्य साधनम् ।
अक्तुं न यह्वमुषसः पुरोहितं तनूनपातमरुषस्य निंसते ॥२॥

As regards the meaning of the word, a classical search in the KST dictionary yields -

Monier Williams Cologne

यह्व॑ mf(ई॑)n. restless, swift, active (applied to Agni, Indra and Soma), RV.

continually moving or flowing (applied to the waters), ib. (= महत्, Sāy.)

यह्व॑ m. = यजमान, a sacrificer, Uṇ. i, १३४ Sch.

Macdonell

यह्व

yah-vá, RV. a. (ī) restless, active, swift;

constant; ever-flowing.

And in Nirukta 8.8, it is thus defined as -

यह्व इति महतो नामधेयम्

Yahweh, therefore means, the great name.
