यह्व / YHVH / yod-he-vau-he /יהוה,

यह्व / YHVH / yod-he-vau-he / יהוה,
--
We find, the above word is perhaps used first time in Rigveda Madala 10, 036/01.
संस्कृत यह्वः (पुं.) / यह्वी (स्त्री.)
ऋग्वेद 1/036/01
प्र वो यह्वं पुरूणां विशां देवयतीनाम् ।
We find, the above word is perhaps used last time in the  Rigveda Madala 10, 110/03.
ऋग्वेद 10/110/03
त्वं देवानामसि यह्व होता ...

The last mention of  यह्व / YHVH /yod-he-vau-he is used as an address to Lord Indra, though Rigveda Mandala 1.164.46 clearly explains all these  devatA are different names and forms of the same Lord (Ishvara)
इन्द्रं मित्रं वरुणमग्नि माहुरथो दिव्यः स सुपर्णो गरुत्मान् ।
एकं सद्विप्रा बहुधा  वदन्त्यग्निं यमं मातरिश्वानमाहुः ॥

ऋग्वेद 10/110/03
Accordingly the above mantra in veda categorically defines 'Who' is 'यह्वः (पुं.)' / YHVH / yod-he-vau-he / יהוה,
I strongly feel this the conclusive evidence that puts to rest all further doubt and discussion, / speculation about 'God'.
त्वं देवानामसि यह्व होता ...
twaM devAnAM asi hotA ...
in Sanskrit clearly means that 'यह्वः' is either the priest to 'devatA-s' or the one who Himself performed vedika sacrifice especially in Agni / Fire for them.
--
There are at least more than 30 places in entire Rigveda, where  'यह्वः' finds a mention.
--
And the first time we find यह्वीः / 'yahwI:' in Rigveda is here -
ऋग्वेद
1.059.04
बृहती इव सूनवे रोदसी गिरो होता मनुष्यो3 न दक्षः ।
स्वर्वते सत्यशुष्माय पूर्वीवैश्वानराय नृतमाय यह्वीः ॥
--
Obviously, this  'यह्वीः' is in accusative plural case of  'यह्वी' feminine.
